@dbamos1945 - I can only tell people here of my experience. I too developed tremors/vibrations while going to sleep, waking etc etc. It was due to Klonopin that a sleep doctor prescribed. Ruined my life for 2 1/2 years. The vibrations are finally gone now for 6 months or better but that was the reason for my issues. So if you have been on a benzo or are on one now, I'd say that could be the culprit. They screw with your central nervous system, just a fact.
