multiple sclerosis
"I was on Betaseron for 1 yr before finally deciding to try something else.  It was effective in the fact that I had no new lesions while taking the medication.  However, I experienced flu-like symptoms after each injection, including headaches, body aches, fever, and chills.  I didn't want to give up on it because everything I read said that this was a temporary side effect.  Anyway, after a year of staying tired and feeling terrible from the medication, not from the Multiple Sclerosis, I decided to move on."
