Just started taking these tablets , I’m experiencing constant indigestion, I’m also feeling more fatigued . I would hate to think how I would feel if i was taking the 4 tablets a day they recommend.

Jaime says:

I took the pills for one day and suffered a debilitating migraine the same evening. I’ve been afraid to try them again even in a lower dosage (2 pills instead of 4) to see if I can tolerate them.
