benign essential trem
"Got Benign Essential Tremor 42 yrs ago. I was 13. Been on primidone 50 mg two in a.m close to 20 years. I just found out it is a barbituate. No wonder I'm sleepy all the time in the morning. Now when I look back I had been vomiting in the beginning. I was even hospitalized for intractable vomiting. Tomorrow I have an abdominal ultrasound because I constantly have GERD and have vomited a lot recently. Meds forever for GERD all sorts of kinds.
I have always let an internal medicine doctor prescribe the med. I am going to see a specialist asap. 
I gave primidone a rating of five because my tremor has never fully stopped it just isn't as noticeable to the public. Occasionally someone will say I am nervous. Then I tell them I have benign essential tremor. Sick of it!"
