... feel so weak, and sleepy, no matter what I do? Even taking amphetimine didn't help with sleepiness or lack of energy (adderall) I had discontinued Adderall, but decided to go back on for a time. From past experience, I should have felt "really" good for a couple of days since I had quit for months. However, not even 30mg Adderall helped me. Could it be the MS Contin. I've been on it for 2 1/2 months, a switch from Oxycontin. Thank you everyone!
