After two weeks on it, it gave me the runs, made me feel like what I just did, and I got to where I could not eat anything or drink anything. Also, I seemed to have increased fatique level. I stoped taking it until I could talk to doctor...I still have upset stomach 2 days after last dose. It did not seem to help the fibro. If I could get my left leg, hip, and knee area to cooperate, I could get more functional. They don't hurt until I start to walk on them. Then after 10 - 15 steps the pain gets almost unbearable. But, I keep pressing on.
