John originally took Propranolol when the doctor thought he had Essential Tremor.When the specialist neurologist diagnosed P.D, he continued to take the Propranolol until recently.At no time did it have any effect on the tremor.He is definately tremor dominant, because apart from drooling (he never did have good mouth closure) he seems (fingers crossed)five plus years down the line, free of any other of the nastier P.D symptoms. Yes, he is a bit slow and drags his right leg a bit, but nothing that stops him running and dancing.He still tremors considerably.
