Try doing (2) weeks of 3/4 dose in stead of going right to a whole dose. That's what my doc had me do. I've been doing the injections since December and I still have the weeks that it is really hard to do. Just remember that it can change your whole life for the better to do it.
Lots of prayers from this Avonex user! If you have a Xanax or something for anxiety on hand it will make the hard weeks easier.
