"in the first  2 weeks of taking these i gained 5 lbs easy. it might just be water weight (i have read that, that is normal) but it is definitely noticeable! in addition to the gained weight i am nauseous all the time and have constant headaches. i am a freakishly healthy eater, i exercise 6 days a weeks and all this has stayed the same. the only thing that i have changed in my routine is the inclusion of this medication. after reading about the experiences of others that are similar to mine i&#039;m going off of it asap."
