That was me.. I hate this disease..
It's been giving me a lot of hell lately...
I've been exhausted too.. and I only work 20 hours a week, and have two classes a week. Feels like all I want to do is sleep.. But, somehow, I only manage a few hours a night due to pain..
I feel for you. Good luck.
PS, B12 injections sound like a great idea.. I didn't even think of it.. I'm going to call my GP on monday and ask about it.
