Propranolol
"This medicine has completely changed my life.  I am basically tremor free, and have been on the medicine for over 6 years now.  My shaking was completely uncontrollable prior to the medicine and I can definitely tell within a half a day if I forget to take it.  Lately I am noticing dizzy and light headedness, I normally have low Blood Pressure and am wondering if it has dropped too low now."
