One week into taking the meds . I did feel anxiety and nervousness. I have never felt those feeling until I have taken that medicine. i also had diarrhea.I started feeling a sensation above my knee where is would start tingling and it would go numb and then start burning after standing for like 10 mins .I have never had any problems with my legs. Then the second week into in the middle of my thigh started a burning sensation. The third week it just kept getting worse . I went back to my doc and told him he said it was my weight and me walking. So Sept 11,09 I stop taking it. I have been off it for like a 7days . the burning has gone down to a soreness in my right leg but my right foot is very sensitive. It very annoying. I do not what it did to me . It has been the worse 1 month experience in my life. I have lost 25 pounds which is great eating right and walking.If it was not for this website and my mother in law I would of kept taking it. Like a dummy. I am looking for a good doctor in
