WEll, now I'm taking quite a mixed brew of meds: 30 mgs of Adderall XR, twice a day, and then 20 mgs of Ritalin, which isn't as long-lasting so I sleep a little better. But I still wind up staying up very late and don't get nearly as much sleep as I used to. Still, without the Adderall and Ritalin, I just can't function. I have Ambien for sleep but I stopped taking it for 2 weeks just to make sure I wasn't addicted. I guess I wasn't. So now I take it again. Pills to get you up, pills to bring you down... it's a little nuts, isn't it?
