I just started getting them last year. I know what you mean. Dr put me on meds had to adjust them because all I wanted to do was sleep until we got a dosage that helped me but didn't put me out day and night. I'm still not as good as I use to be it's very irritating, but its part of my life now so I just accept it and hope it doesn't get any worse. If so its shotgun time!
Stand closer to the toilet?
Tremors run in my family. Dad had 'em, both of my brothers have 'em, and I have 'em but not too bad yet. Rifles get shot off a rest so no issue there. With handguns, I have started using a technique that works well for me. Press firmly forward with the strong hand and pull back firmly with the off/support hand. Worth a try.
I guess it's a relief that I'm not the only one suffering from this. It started a year or so ago, and is often bad enough that I can't sign my name with any degree of legibility.
You might see a neurologist.
