I was prescribed propranolol (beta blocker) at one time to help with anxiety. It is often used by musicians and actors to curb
stage fright. It has something to do with adrenaline receptors, and apart from lowering blood pressure I think it curbs the effects of adrenaline, which is what causes tremor in anxiety.
Unfortunatly I have been taken off that as my GP did not like it as a long term solution to anxiety and now I am on lorazepam instead, and no that doesn't stop the tremors.
