"I started using this in combination with propranolol for my tremor. I take 80 mg of the propranolol in the morning and 50mg of Primidone before bed. I had been taking the propranolol for 6-7 years already and it cuts the intensity of my tremors by 50-70%.  By adding Primidone as a combination therapy I would say that it's 80-95% reduced.  If you have a hereditary tremor like this you should ask your doctor about these medicines.

Good Luck!"
