Ugh, tell me about it. I took some Dexedrine earlier today (think 13 hours ago) with a cup of coffee, and then took 2.5mg Adderall 6 hours later, and then another 2.5mg Adderall about 2 hours after that. Worked well with 1mg clonazepam but now the Dexedrine is long gone and the Adderall is pretty much gone too. I know because I get really horrible back pain, lower back pain, when I'm coming off Adderall. It happens with Dexedrine, but is much more pronounced with Adderall for whatever reason (lousy levoamphetamine!).
I'm staying hydrated and took 500mg magnesium with some fish oil as well as a regular old multivitamin today but it still isn't seeming to help

Bad times, plus I'm exhausted.
