Benign Essential Trem
"I have been taking 250 mgs of Primidone for the last 17 years for Benign Essential (What&#039;s so essential about it? ) Tremor. As far as I know, I have no side effects. When I first began the medication I started out with a smaller dose and worked up to 250 mgs. I found that I could not take the meds during the day because of sleepiness, dizziness, etc, so my doc suggested that I take it at night. I have been taking it at bedtime since, and it helps to put me to sleep."
