I have been using 37.5 Phentermine for about 7 weeks now. I have been very overweight for my whole life. I was 6' 326 when i started. 7 weeks later i am down 28lbs and feel like a different person already. You have to want to change your life when you start this. Everyone asks me if I'm on a diet and I tell them no, I have done a lifestyle change. This is critical becasue diets end and you will more than likely go back to bad habits if your not commited.

My doctor gave me phentermine about a week ago and it absolutely does nothing for me. About three days ago I started taking 2000 mg.of vitamin B-12 with it and it still does nothing! I really thought that this was the final answer to my losing 40 pounds. Help, I do not know what to try next!

I will be starting Phentermine next week 8/29/11 and I am 5'8 and 205 lbs.

To be considered 'healthy' I need to be no more than 170. While that is my goal, I would love to eventually reach 155-160. I live in MD and will be going home for Xmas this year in CA to see all my family. I am hoping to show great results by the time I go home so I can surprise everyone.

I am excited to see results much faster than anything I've ever done in the past. I'm also a little nervous about the idea that I might actually drop a considerable amount weight. It's been almost 9 years (and 3 children) since I weighed 160 and I don't have any idea what I'll look like anymore at that weight.

I've read extensively about this pill, its side effects and numerous results and I am completely willing to dedicate myself to making all the tests and effort it took to get the prescription, worth every minute. I plan on continuing and increasing my exercise and watching my diet to make my 'healthy' goal.

All I have left to say is: "BRING IT ON!"

Second day, have some side effects but am also taking another pill that increases those effects. I expect to level out within the next week. Drinking tons of water, not hungry at all. Like another person wrote, for the first time in my life I am not consumed with obsessing over food. I have energy, but my heart rate is up a little. I am still in the normal range. My blood pressure is borderline, but once my body regulates to the meds, I will be in the gym again. I don't crave junk food or alcohol at all. I do crave salads, and sometimes whole wheat bread or a breakfast bar. I have lost 4 lbs already. I have a LOT of weight to lose. As has been stated, this is NOT a long term solution. This drug is about creating healthier living habits. Healthy food, exercise and moderation in everything. I love it so far.

I am 21 years old, 6"0 and started phentermine at 229 lbs. Started March 2nd and ended May 26th my personal goal was 170 and I made it to 178. Phentermine definitely works, its amazing if used right with diet and excersize it'll definitely help you lose weight. it changed my life, and even off the pill I have managed to continue losing weight with the diet and excersize plan I did whil on the pill. As for side efffects, for me, they were really severe the first couple of days but after that it was barely noticeable. The only caution is, you will lose so much weight people begin thinking you are doing drugs! Very aggrivating! Good luck on everyone starting their weight loss journey. I will tell you this, its much more of an emotional ride rather than a pyschical one. Thus far I have lost 54 lbs and am a completely different person, socially.

I am severely overweight. I am 5'8 and 315lbs. I just started taking Phentermine two days ago. The doctor started me on 15mg for a month and then go from there. I am starting to drink lots of water and getting my eating portions in half. The only thing I still have cravings but I think that is because I am on such a low dosage. My goal? I just wanna lose enough weight to play with my boys. They are very active! I am shooting for 30lbs at first and then go for 50lbs.

Been taking phentermine 37.5 for about a month and a half now. Only down about 7 lbs. :( I eat very carefully and exercise everyday, lift weights and cardio. Seems others have much better results. I am wondering if anyone else suffers from hypothyroidism?? I do and take meds for that as well. Dr said birth control pills may be making it harder for me as well. Any others with experience with this, your thoughts would be greatly appreciated!!

I have been on Phen for about 3 weeks now (6/27/2011) and have lost 16 lbs! I started out on the 37.5 mg but decided it was a little too much. I had absolutely no appetite and if i did eat, it was veggies and fruits and an occasional peice of lunch meat. Going to the gym and doing cycling classes and zumba was just to much to do on that little bit of nutrition. I was getting sick after workouts. So i decreased my dosage of Phentermine to 15 mg and am still losing the same amount of weight a week. Starting this medicine has motivated me so much! I feel great on the new dose with the excersize. My goal is to lose 50 lbs. I started out at 206 lbs and am down to 190 :)

I started out on Phentermine 15mg 1xday since Feb 22, 2011. Today is 06/09/2011 I have lost 39lbs and have now switched to 2xday, but I dont always take the 2nd pill. I really am happy with my weight loss so far. I hope to lose 100lbs using phentermine. Once I lose the weight, I would like to start using exercise to maintain the weight. Which shouldnt be to hard, bc I have learned how to eat..what works and what doesnt work as far as weight loss. Phentermine is awesome and I would suggest it to anyone that needs to lose weight.

Female wt 196 ht 5'2 started date May 30, 2011. Today wt 191.2 ht of course still the same lol 5'2. My goal weight is to get back down to 160 yes I know thats still over weight for my height and age 20 something but that's my goal since I haven't seen 160 not even 189 in over 5 years. So, this is a big step for me. I am currently taking phen-8mg twice a day sometimes once a day. I know you guys are saying, 'why 8mg?' well, I was taking phen-37mg but due to the side affects (appetite suppressant ) I wasn't barley eating a whole apple...I went from eating popeye chicken, pizza, banana pudding, chocolate cake, chocolate ice cream, pasta and cheese cake, which is all my favorite foods, to eating three small light meals which I have to force my self to eat and fruits to snack on in between. I do 15 min of cardio everyday and here I am today Sunday June 5, 2011 weighing 191.2 pounds yeeee! Phen is definitely a miracle pill for me.

I was on Phentermine about 7 years ago. I had tried every diet and diet pill and aid up to that point, with no success. Many of the OTC diet pills made me "shaky" and "jittery" and sick to my stomach. I lost approx. 15 pounds back then within about 2 months and never experienced any major side effects. The only effect I encountered was dry mouth. I was on the 30 mg. pills. I have since, in the past 7 years, put the weight back on and then some. But, I did not gain the weight back immediately after stopping the pill and I gained it back because I went back to unhealthy eating habits and no exercise. My new dr. is starting me on the 15 mg pill now. I hope I have as much success this time around as I did last time. I'm looking to lose about 22 pounds and have a new healthy routine of eating.

I have been on Phentermine in the past and lost 40 lbs. I am back on it and just got weighed in after 4 weeks and have lost 16 lbs in 4 weeks! I walk daily about 1.50 miles on my treadmill and have cut my portions in half. I have find that if you cut certain things out of your diet you crave them more, so just eat smaller portions so you can still enjoy those favorite foods. I go back to my dr in 3 months.

I started using phentermine on April 20, 2011. So I have been on it for 15 days and lost 10 pounds according to my weigh scale. I cut out the sweets and soda. It seems like when I used it 2 yeas ago it was easier to lose the weight, and I was not hungry. But this time I get hungry a lot. Anyone who has used it more than one has the same experience???

Does anyone know the difference between Phentermine (white w/blue specks) and Phentirimine ( blue & white caps.) ?

I think the internet gets you to think they are the same but I don't think so.

I have used this medication about 2 1/2 yearsa go. It helped me lose 31 pounds in about 4 months. I ate Smart Ones, a lot of apples when I was still hungry, and when I wanted a treat would eat 2 dark hershey kisses. When I lost the weight I got pregnant. Now I am back on it, today is my fist day. I am hoping for better or same results as the first time. Somebody asked if this will interfere with pregnancu, no it will not. Just be careful that you do not get pregnant while taking this medication. When I was pregnant nobody knew about side-effects. LAst friday when I had a Dr. app. I asked her and she told me that it may cause hypertension in children! So heads up for those who are planning to have a baby!
Good luck to everyone!

I started taking this amazing diet pill in September of 2010. I throughout the whole time i was on it i was only taking a half of a pill except one month i took a whole pill. I am very overweight. When i started in september i weighed in at 280. In January i was down to 226. My goal weight is 160-180 for some that is still overweight but I am very big built and have been BIG all my life so i dont want to look sick.

During my time on the pill I didnt work-out much i didnt have time but i could only imagine how much i would have lost if i had been working out. I recoment this pill to EVERYONE I talk to about weight loss.

I have been off the pill since the middle of January and by geez i can FOR SURE feel the difference. I have also started gaining weight back prolly 20 pounds :(

The only downside to this pill is if your body isnt fully adjusted when you get off the pil the weight will come right back on QUICK!! Most people when they get off it gain back more than they had lost in the first place.

Good luck to those looking to try the pill and everyone wish me luck getting to my weight goal!! I will update everyone as i get my results from my doctor.

I started gaining weight when I was 19 years old after trying several different medications for PCOS. My weight sky-rocketed and i've struggled ever since. I heard about Phentermine through a friend and decided to ask my doctor.
I started Phentermine in December 2010 weighing 251 pounds, i'm 5'7 and 24 years old. It is now April 2011 and my weight is at 217. I don't work out regularly but am planning to start. My blood pressure has dropped and I feel amazing. My goal is to get to 180, I know that's still high (to society) but i'm built like a line backer anyways lol.

The side affects I have are dry mouth, blurry vision and restlessness. I think this drug is a gift, I highly recommend it to anyone. I take it first thing in the morning so the jitters where off before bed time. If anyone needs any help or answers, please ask. Good luck everyone!
