I have had tremors in my hands, arms shoulders and upper chest and legs for at least four years.
Neurologists continually prescribed stronger and stronger medication which sedated me to the point where I could hardly function.
The main University where I live has set up a separate clinic dealing with people that are affected with "Body Motion Disorders".
I have a body disorder that has not been identified as yet. New MIR tests should possibly point me in in the right direction.

Now, on to your question about something to stop or settle down your tremors.
CLONAZEPAM is the only one I would personally recommend.
I have been using it for a over two years and it works wonders when the shakies/tremors or whatever we call them show up.
I take a 0.5 mg tablet as required. I take them as I need them which is not a regular basis. Someday one pill does the trick other time I take more. Depends on what I have been doing. Slight labour will get things going. Which makes me useless in using a keypad or simply trying the handwrite a note or take down a telephone number.
Best of luck to you. CLONAZEPAM, you have nothing to lose.
