I have been taking Dexedrine 15 -20 mg. (currently 15mg.) for the last 12 years. It works great. The doctor did put me on Provigil for a time. I went back to taking good-old Dexedrine because Provigil did not work as well and the cost was extremly high.

i never heard of dexedrine. i will have to ask my dr about it. as provigil does allow me to become very tired.
