Was this an extended release verson like Vyvanse? I had an absolutely terrible time with that for the same reasons. If that was your experience with plain dextroamphetamine, totally sounds like it's just not meant for you!

I tried the three big ones: regular Adderall, Adderall extended release, and Vyvance. None of them really helped my focus and all three really screwed with my sleep.
