I have been off C since last August and feel so much better off it. I used C for three years. I also quit my job in September....way to much stress which did me in. Pain in my left leg which was driving me nuts, tingling in left leg, heart palps every second of the day and my memory was toast..couldn't remember anything. Most of my symptons are gone and I'm feeling better than I have since I was dx three years ago. I do not care to put any of that crap in my body again, I feel that I was worse off with it. Everyone is different though, it's all personal choice...a very expensive choice! Good Luck!
