Anxiety - need some relief in Cocktails - Medicated to the Gills and Floundering Posted November 15, 2020 I've had muscle spasms from antipsychotics before. I took propranolol for it, I think. It was a long time ago. I have absolutely no idea if that is anything like what you have, your doctor should be able to tell. They have been able to get me in sooner with certain side effects, and they'll probably get you in if you're miserable enough that you have to experiment on your own.
