MS fatigue is real. If you don't have it, raise your hand!

It got so bad for me prior to DX - I had to sleep 12-14 hours per day. With 8 hours at work, my life shrank very quickly. House was unkept. I felt behind on all kinds of paperwork. The door was wide open for depression to set in.
6 months after starting on DMT, I felt I was alive again. Don't get me wrong, I do need to sleep a solid 9 hours. But at least I can function well. Once in a while, when I do too much, I have to spend a day in bed. But nothing like prior to DX.
