I'm on 300mg lamictal, 30mg vyvanse, 60mg buspar. I dont feel over medicated or sleepy thanks to the vyvanse. It doesnt go **** for when I'm manic but I'm learning to deal with that. I just couldn't handle being depressed for months at a time anymore. I wouldn't recommend doing it without meds at all since that's when many people go off the deep end like my friend that hung himself in his front yard. Hang in there.
