Follow-Up: On Aug 28 I will be on Provigil for 1 yr. I have MS as well as the Myotonic. I also take Amantadine. I take both when I first wake up. Then I will lay down again until they start to work. My husband said he sees a difference, that after I get up with the pills in me I do seem to have more energy. But I still need a lot of sleep. I have fallen asleep in a chair. It seems to be that I need to nap after dinner. What I would really like to know, since I gave our son the Myotonic and I have both the MS $ MD, Will he be more likely to get MS also?
