Have you tried googling the side effects of that stuff? I've had internal vibrations since 2019 and my neurologist thinks it's from an overactive central nervous system. I think it's from injury to phrenic nerve. Last night makes 8 nights with no vibes. I use nasal cpap for minimum 4 hours before bed. The only time I had issues with insomnia is I didn't sleep for over 48 hours or eat for 5 days when I had withdrawals from stopping xanax suddenly. I haven't got a clue, only that there seems to be a lot of people with these vibrations and no answers.
