"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'm going off of it ASAP."
