Tremor guy here too. Gets me sometimes on ghost notes when I'm nervous. Some things of note:
I've found some good resources on the essential tremor
Subreddit.
Meditation and non-sleep deep rest have helped me immensely to calm my body on a deep level. Breathwork, polyvagal nerve stuff, sleep hygiene, and a ton of related things have given me markedly noticeable improvements.
I found bigger sticks with small tips to work nicely. I use VF Boleros because they have a small tip but are big enough that I don't have to keep something delicate from wobbling.
I take Lionsmane, NAC, Magnesium Glycinate, high EPA Fish Oil, vitamin D, and low dose Naltrexone (like 1.5% of normal dosage) daily. I want to be clear that I'm not suggesting to take those, but simply that there is some relief to be found through supplementation. I've worked closely with my doc for 5 years with lots of trial and error to settle on that, so should you decide to throw supplements in the mix, I'd suggest doing it in that manner.
Worth getting a blood panel done to check for any mineral deficiencies as well.
