I'm no Dr, but that sounds like type 2... I think Miguel'smom is on to something. I can honestly say I've never experienced feeling flat on meds, except during depression... either way, hell. But I run HIGHLY manic like 80% of the time... my guess would be either meds too high, or possibly wrong med entirely. My mother used to get flat on hers, and a friend I've long since lost touch with would always stop her lithium because of that. The docs would always just taper them down.
