I have been diagnosed with Essential Tremor. I was on Propranolol for a while. It helped a little, but I felt like..... the whole time. I got off that and currently take nothing for the condition.For shakeyness you can try a beta-blocker. Talk to your doctor and he may tell you to take 20mg 30 minutes prior to shooting ant it may help. It does with a condition know as essential tremor as well as other nerve issues.
Propranolol is the best for this and it is generic. $4 script at walmart
I do try to make sure to get enough rest, and that really helps as much as anything. Secondly, I try to keep the caffein intake as low as possible, but if I get self conscious, or nervous, and have had caffein within a few hours, the wife consistently out shoots me.That's my story an' I'm stickin' to it!! (the only advantage to ET is that you have another excuse in the arsenal)
At the range, shooting technique is king. I do use a left handed, bent arm technique, wierd-oh modified Weaver stance in an effort to learn to control the shakes and get a good shot off. It does produce some semblance of a group.
I intend to ask the neurologist to try a few other things, but I don't hold out much hope for the chemical route. Not much help,I know, but just my experience. Getting old is only for the tough!!
