Is it possible for sleeping disorders to be genetic?
I have always had on the little side of sleep, all my life. Sometimes I'll just stay up 40 hours, then go to sleep. (I have done, do, drugs. BUT, like I said, this has been all my life, since I can remember). I honestly do not mind it, I enjoy the night time, and I get a lot of house work done, but I realize it can be unhealthy.

My dad has had some sleeping disorders before. From insomnia when he was younger, to having sleep paralysis.
Did I get it from him?
