Primidone
"I was diagnosed with ET 6 weeks ago. I was prescribed Primidone. To date, I still am having serious side effects. My tremors are continual, even to the point where my left arm feels "dead". Generally I feel drained, dizzy, and sick to my stomach. My voice is halting, with shaky patterns, and is more affected when I am tired. I find it very difficult to take this medicine and will be calling my Doctor to discuss any other options."
