sleeping 16 hours a day

Hello everyone. Sorry for my bad english, please, i'm russian.
I'm new here. I've been sick with this disease for about 3 years, but i almost didn't do anything to heal.
Usually i'm sleeping 12 hours a day, but i want to sleep 16 and sometimes i do it.
You see.. when i'm not sleeping for 8 hours, my brains start to work bad, reality goes away from me, i'm feeling completely dumb and i want to sleep very much. It's tough also to wake up and i'm sleepy during the daytime.

Recently i healed my schizotypal symptom - derealization, - with haldol. So now i'm going to try to solve this problem.
I will write here about researches i'll do and which results i'll receive - this will make me try more hard.
Thank you!!

Please don't try to diagnose and treat this by yourself. See a doctor. Have them test you. There can be many reasons for this sleep disorder. Some reasons can be physical and haldol won't help those.
Haldol can be a very powerful medication and must be monitored by a physician.
Best of luck to you.
