Follow-Up: ihave just been prescribed provigil to treat the fatigue i experience due to ms. i have taken it now for one week! the first day was great. i was so excited, it was the first day i had stayed awake in months. since then it has gone down hill severely. i have had to nap 2-4 hrs a day in the afternoon. missed one day of work and slept all day. hope this is just a period of adjustment to the drug. i think i feel worse now than before. nancerella
