I don't know if it is clozapine or gabapentin or the combination (probably) but something makes me pretty tired. I also have broken sleep so it takes more hours to get enough sleep. According to my fitbit I get about 10 hours per night and I'm trying to sleep 12-14 hours to get that on average. My sleep has been screwy since 2 days after I came home from the hospital after I was born so it's hard to know for sure. I just know that maintaining sleep however it takes is vitally important for me.

Don't mean to scare you off. It's totally worth any side effects to me and I honestly doubt it's that sedating for most people based on talking ot others taking it or who have taken it.
