I think that's a pretty small dose. Drowsiness is a side effect I read, I'd maybe try the non time release, so you don't get some so close to waking? It made me feel groggy when I woke and didn't really seem to help that much when I tried it. Have you asked your doctor how much to take; it can interact with meds, etc.
