I have no advice other than give it time. Let it bring you down for a while and then maybe you can talk with your doc about easing up on the dose. I'm not familiar with that drug but it seems like a high dose meant to pull you out of mania. Maybe they would be ok with just twice a day soon.

Hugs. I know what it is like to feel zombified and in need of an all day nap. It isn't a good feeling, but it is safer than psychosis.
