Oh, cool! I sent out the link to this site yesterday, and I've already gotten emails!
I have been absolutely wiped out since last evening. Yes, I went to the pool yesterday, but I either stayed in the cool water or stayed in the shade the whole time, so I definitely did not get overheated. I still felt fatigued this morning, even after a solid night's sleep. I did read that weakness and anemia are side effects of Avonex, so I've been trying to pay extra-special attention to my eating habits today. That roast beef sandwich tasted very good at lunch - gotta get my iron. Hopefully this fatigue will subside soon.
