I think its fairly common, give it a while and see what happens, it seems like smaller people and especialy women take a little more to adjust.
I am on day 4 of Adderall 10mg. I have noticed that my muscles seem to be tensed up. When I type or drive, it is like I have a death grip on everything.
In the evening, if I sit still, I feel like I need to stretch my legs or shift them around, almost like people describe with restless leg syndrome.
Anyone else have a similar experience?
