Just started on Adderall XR for my ADD (20mgs per day) 2 days ago, the first night I went to sleep fine (not surprising seeing I take 50mgs of Seroquel and 40mgs of Prozac at bedtime), last night thou no sleep at all till 7:30 am because my feet and calves keep cramping... Any ideas why?

I took my adderall at 9am both mornings so I guess the 20mgs had mostly left my bloodstream so I'm a little perplexed. I also take 15mgs of Prednisone for my PMR, but I have had no noticeable adverse reactions to it or any of my meds that I can think of.

Sorry if I'm rambling a bit, but the site suggested I give you guys some more details.. :)
