Restless Legs w/ Adderall XR? | ADHD Information

I just started taking Adderall XR yesterday.  20mg.  Last night was crazy!  I was so wound up, running around doing all kinds of "normal" things, feeling very "accomplished" for the first time ever...then I hit the bed and my leg were very restless.  Perhaps I took the adderall too late in the day?  Perhaps I am going to have become some what accustomed to the medicine and it will stop?  I did have a rather difficult sleep, but that was worth the progress I made in my home and with my family yesterday.  Ideas? Thanks!
