It could be the meds too you don't know. i thought i was that way when i was on zyprexa and I would sleep 16 hour days on 15mg... when they put me on Invega I stopped sleeping altogether... so it couldn't been that... same with vraylar but i was on haldol as well as vraylar... it just didn't work out... then i was on haldol and was sleeping 12 hour days... sometimes more but i was on a high dose of haldol.
