Welcome Crittle!
I have been on Avonex for over 7 mths. I am not the norm...let me repeat...I am not the norm. Most folks side effects get better after 3 months. Do you pre-medicate with advil or tylenol and then take it every 4 hours or when you wake up?
I know a few on Avonex besides me that are doing really well with the side effects, very mild. Hang in there. Make sure you are well hydrated the day before and the day of your shot. Also, try to be well rested . I hope it all goes very well for you. Are you giving yourself the shot? Hooray for you if you are, I have to have my hubby give it to me, I wish I were able to give it to myself.
Take care and keep us posted.
