HI, I was diagnosed (officially) in 1994. I used to have RRMS, but at some indeterminate time (around '97 or '99), I guess it turned into Secondary Progressive.
I first was on Betaseron for seven years, then that seemed to not be as effective all of a sudden. Then, I was on Copaxone for a while. Then I was on Novantrone, which almost seemed to turn back the clock a couple of years! After my three years was up for that one, I took Rebif for a few months, until I could start Tysabri. I had two infusions. On a Friday, I had my last infusion, and that Monday, they pulled it off the market.
Now I am back on Copaxone.
I didn't feel fatigued when I was first diagnosed. I had optic neuritis, and I found one day that I couldn't run anymore. I had a preliminary "probable ms" diagnosis when I decided to have a baby. When my daughter was fifteen months old, I had the MRI that proved the diagnosis. I was fatigued at that time because I was a stay at home mother of an infant.
About five years later, the fatigue which I was feeling had a different flavor. Now, I get tired easily. My head hurts when I try to learn new information. I loose my temper easily, because I feel like I am being tortured when I am just trying to finish something (anything) which I started. So, it would be nice if we could choose to combat fatigue and control it by exercise, and I am sure that it can be helped a lot by regular exercise (because I do that), but you can't make it go away entirely. Just do what you can, and don't let it defeat you; but don't think you have won either. It doesn't go away.

Aren't these emoticon thingies entrancing?
