How do you sleep on Phentermine??

jenny asked this question Aug 30th, 2011 5:36 pm

I took 15mg for about 4 days, the side effects were fairly mild, but the worst was that I could not sleep. I ended up having to drink, so that I could relax enough to go to bed. I knew I could not continue like that, although I was seeing results. Is there any solutions for sleep aids/sleeping? Should I ask my doctor to decrease the dose? I am currently 5'2 153lbs goal - 130lbs.

I've been off and on Phentermine, first time was for wieght and now its for energy due to chronic fatiuge but the best way to help you with the trouble sleeping is to take very early in morning but to also be as active as possible thru the day,, the more energy you use the more you will lose along with the faster the pill will burn off in your system. You can also try a half pill in morning and see if that works as well as one pill,, sometime it's enough at half dose, when it starts to not work go back up to a full pill.. Good luck (-; sarah diamond

Lower your dose. Start of 15 mg one day. then only half that for two days. Always early in day. Skip a daym then skip two days. When take only half of 15 mg. Use little possible dose. If you relapse, start over. Melatonin or Benadryl (simply sleep) ok.
