I can tell you what works for me. being very sleepy. This is how I do it: When I plan on going into sleep paralysis, I only sleep 3 hours that day. Then, stay about 15-18 hours awake. Fight your body to stay awake. Try not to drink coffee or caffeine products. Then When Its time to go to sleep. Your body is so use to you staying awake that once you lay down and try to sleep, your mind will stay awake and your body asleep. Usually before this happens, I tend to feel electricity in my head. Throughout the years, I have been fighting to not be scared when this happens but practice makes perfect. See if that helps.
