I also have essential, or primary tremors. The degree to which they occur vary considerably, based on factors I can't figure out.
I've taken propranolol, which is taken on an as needed basis, but currently am on a very low dose of primidone, which is taken every day. I'm also on metoprolol for blood pressure, and while it supposedly does help the tremors, it's not as effective as propranolol. Both the beta blocker and primidone are in fairly low doses, so it might be worth talking to your doctor about. As I said, the propranolol you only take when you need it.
At times my handwriting is embarrassing, but I ignore it. Other times I can tell people notice the tremors. I ignore that too. I also seem to have balance issues, but the dr. hasn't said if that's part of the same disorder or not. I imagine it is; at least the symptoms correlate in time with the increased tremors.
Stupid/funny story: I was writing out a receipt for a cash payment of rent from a tenant and my tremors were moderate then. My writing was shaky, but legible. He said "I can see you're scribbling it so it can't be read" and some comment about that leaving the door open for me to do something dishonest. I handed him the pen and receipt book and told him to write it and I'd sign it. Ignorant fool. The irony is, he wanted to leave me the cash in an envelope. I insisted we meet in person and I give him a receipt. Ignorant fool. Oh yeah, I already mentioned that lol.
I did once go to an occupational therapist who specialized in movement disorders. There are some techniques you can use to mitigate the effects. Also, some special items, like a heavy pen or heavy fork/spoon. The weight acts as a ballast, which supposedly reduces the tremor. I didn't see much effect myself, but as they say, YMMV.
I just recently read about some ultrasonic treatment for it. I have no idea what that's about.
Good luck with it. Lots of us have it; you're not alone.
