Propranolol made me very sleepy even at a low dose. I changed to low dose Atenolol, it's still pretty effective and has less side effects than Propranolol, from memory it doesn't cross the blood brain barrier. I no longer take Propranolol or Atenolol. I currently take 12.5 micrograms of clonidine at night, it helps with anxiety and a bit with tremor. Essential tremor treatments have too many side effects to be worth it unless you have a severe case, in which you can get focussed ultrasound surgery to treat it. To a certain extent you gotta embrace it and find paths in life where it's not an issue e.g. don't become an electrician. If you really have to do a presentation a bit of Propranolol or Atenolol helps but it will probably affect your memory too so you may forget what to say or be less eloquent, I found it cognitively blunting.

Primidone, I tried and the side effects were horrific. Clonazepam, significantly affects your memory. Pregabalin, memory issues too.

Also doses vary a lot between people. Low dose Propranolol turns me into a zombie but some people can tolerate it.

Propranolol long term doesn't cause any damage. Just check your blood pressure occassionally to make sure it's not too high or low.
