In regards to sleep, I am the same way taking about an hour to go to sleep right once I hit the bed unless if I stay up really late (which I can only do successfully on the weekends). One of the greatest things that I've found that makes me exhausted is taking two calcium pills two hours before I plan on going to bed. Calcium acts as a natural tranquilizer and makes me feel so relaxed. I would highly recommend you look into that.

I have also noticed, which my father also let me know, when my body lacked a lot of water/oxygen is when I would get into sleep paralysis. For me, I've become very accustomed to drinking a lot of water on a daily basis and it is very simple for me to get dehydrated if I don't drink 6 glasses of water or more a day. When I'd take naps dehydrated, I always got sleep paralysis.
