Interestingly, my vibrations have almost completely ceased. They had faded in severity over time & I haven’t noticed any in months, with the exception of my right hand. I am right-hand dominant, in case that matters—but I have not even the slightest hint of a tremor in my waking life with that hand. Also, I only notice it when I bend it to put it underneath my pillow. I can be sleeping on my side or my back & experience this tremor in my bent arm, either way. So, I’m happy that it’s now limited only to that part of my body & only in that position. I have gone months without these tremors (elsewhere in my body—mostly my neck & head) before they came back, nightly. But, as of now, I am almost completely sleep-tremor-free. I will note that I stopped drinking alcohol since last October-ish, and hadn’t thought about the connection with the tenors stopping, but maybe there’s something there.
