I have taken:
Ritalin - not helpful to me
Provigil - headaches and not helpful
Adderall - Somewhat helpful. I had been taking 10 mg 2-3 times a day. I am now trying 15-20 mg twice a day.
I take the stimulant 2 hours before I get up for the day, as it seems to take that long to kick in, even as an immediate release formula.
