I started Modafinil last December but I honestly cannot say for sure if
it works. I still get tired but
it does not seem as bad as before I started
it. Some days I don't take it at all and seem fine, other days I don't take it I am exhausted.
I switched about 3 months ago from Rebif to Tec. Like Lori, I had to go back and start more slowly due to severe GI issues. I have been back on the full dose about 3 weeks and it is a lot better than before.
