Just reread your post and noticed you mentioned beta blockers. I was similarly prescribed because of very noticeably shaky hands. Not a good look on a flight deck! I had to hold a cup with two hands to reduce spillage! However, I was not happy about taking them and a google search confirmed (to me) that unless you really must take them, then don't. They can create additional problems of their own. Since I was off work anyway and shaky hands weren't so much of an issue, I stopped taking them after a week or two. The shakes subsided to zero fairly quickly anyway as the Thorazine(?) level reduced toward a more normal level. To be clear, I am not medically qualified in any way. These are just my feelings and experiences.
