Body vibrations when falling asleep or waking?

I am happy to find this discussion! I have had vibrations when I am semi awake/asleep for over ten years and never been able to find much about them. Just that was possibly caused by adrenaline surge due to fight/flight response. I have always worked nights and it happens at times when I have been most sleep deprived when I am either just drifting off or briefly waking. However...I have very occasionally had them when fully awake, but when I've been up all night and not hardly slept during the day.
At first I thought they were linked to a cancer which was diagnosed, they seemed to stop after I had curative surgery. When I started having them again I worried but luckily yearly scans put my mind at rest. I would love to know exactly what they are, I've never met anyone else who experiences this so it's great to read all this discussion.

I'm about to research metoprolol as the culprit. It says it crosses a brain barrier that atenolol does not. I used to take atenolol until an ER doctor changed it to metoprolol. I've got to call office to see exactly when I changed to metoprolol. Last month, I ran out of metoprolol and started taking the atenolol I had left. I went 9 nights with no vibrations. This morning I had the vibrations, about a level 3, and I've been back on the metoprolol for about a week. I'm guessing there was time for atenolol to get out of system and metoprolol take back over. I'm wondering if other people with vibrations may be taking medication that affects the brain the same way metoprolol does. I really need to talk to my cardiologist. If these vibrations start back nightly, I may switch back to atenolol. Researching.
