Maddieg,

Another thought:

If your dose is too high (for you) then you can also experience the crash at the end of the day.

I take Adderall, but only take half of 5mg dosage because it makes me too jittery. Provigil made me like a person on too much caffiene.

I took Ritalin when I was younger for fatigue it worked well, but Adderall works very well for me.
