Hi there,
Sorry you are experiencing this. I am with homebrews. Try those suggestions and if nothing seems to help and they are still there, go see your doctor. Good Luck
Sounds like hypnagogic jerks. It's extremely common (happens to around 60% of adults). Try to avoid video games, watching extreme movies, tv, etc right before bed...instead try reading something. You can also try some chamomile tea or valarian root to help knock you out faster.
Yes. I used to have this all of the time. I would jolt awake or wake up with my body vibrating.
