My husband was debilitated by fatigue....he actually had a car accident when he feel asleep at wheel, and he was unable to work. This was truly life-altering fatigue, and the provigil has been a blessing for him for the last year. He takes 100mg at 10am, and 100mg at 2pm and is able to function. He now works mainly at home, and is able to stay awake at his desk. It's not about being simply "tired"...it's about living. He has so much to offer in his profession, and cannot imagine retiring at 45. He still needs naps and rests, but does not fall asleep driving anymore.
When I wrote and explained his profound level of fatigue, his insurance (Blue Cross) reversed their decision, and agreed to pay. It may be worth it to you to follow up on this since you need to continue working.
Fatigue comes in all levels...and for some with MS, it is intolerable.
wishing you the best-
