Multiple Sclerosis
"While the Avonex was extremely effective on the lesions (they became smaller and some actually disappeared!).  However, the side effects were severe. It literally took me out for 3 days (totally) it took about 2 more days to do anything above the bare minimum i.e. go to work, come home, eat and sleep, and I had about a day and a half to get everything else done such as grocery shopping and mowing the yard and taking out the garbage.  Let alone housekeeping.  I finally just switched to Copaxone due to anxiety over injecting the drug with such a large needle and to counteract the side effects of Avonex."
