The reason I know about it is that I had it myself a few years ago. I was always very embarrassed by the shaking hands.. and the occasional shaking head.. . At first I was concerned that it was PD because my father had that.. and ultimately died from the effects of it, ..and I thought I might have inherited it , but no, I was reassured that it wasn't, and that BET is not fatal... embarrassing.. annoying, but not going to kill me..
I was put on Clonazepam.. and was on that for about 2 years.. and then suddenly for whatever reason no-one understands.. the Benign Essential tremors stopped..
I still get it very occasionally if I carry something heavy.. and then my hand won't stop shaking for a few hours, but otherwise..touch wood... it has never returned..
