Primidone
"I have what my doctor calls a mild case of benign essential tremors, but when I'm trying to practice or perform with my guitar, or do electronic work with small parts, its become more than annoying. Proprananol works, but as an asthmatic I have to avoid it or I'll wheeze. Doctor gave me a small dose of primadone, 50mg, and told me to cut some pills in half and just use 1/2 for a week or so first). I don't know if I'd get used to this stuff over time, but unless I'm willing to forget about musical performing while I wait, I'm going to have to stop. I find my coordination, speed, concentration, ability to remember song parts and lyrics severely hampered. It does reduce (but not elimate) the tremors, but what good is it if I can't do my work?"
