multiple sclerosis
"I have been on 20mg for about 6 years. Some annoying side effects as itching back, and feet, muscle spasms, tingling but could pretty much handle them. Then went to the 40mg. Not good. For a few months was okay but then the severe heart palpitations, Tingling in head and face, muscle spasms that would would wake me up. Neuro said was not meds and kept giving me something for anxiety. Nothing helped so I figured it was me and would have to live with it. Decided to go off and see if that helped. Has been a week and a half and I feel the symptoms fading away already.  Don't know if I will go back to 20mg or just stay off of it.  I can't live with the harsh side effects of the 40mg."
