How do you know when it's "fatigue" hitting you? I don't know if I am finally getting the dreaded fatigue I have read so much about or if I am coming down with something. I am recently diagnosed, been on Avonex for 2 months, and have felt pretty good until a couple of days ago. I have only had minor flu like symptoms from my injections that last about a day. But now I am really achy (injections are on Monday)- in my back, arms, legs and am extremely tired, yawn alot

but I'm not necessarily sleepy. I also have an empty "pit" feeling in my stomach. It is so hard to describe these weird MS feelings, but I am hoping someone has had these feelings and can clue me in. Of course these things always happen when my neuro is out of town.
Frustrated!
