thank you dr. I have essential tremor, not Parkinson's disease. When I hold a glass of water, my hands tremble and I feel embarrassed. When a problem occurs in front of me, my body trembles, my heartbeat increases, and I find it difficult to speak. A neurologist prescribed an anticonvulsant drug (Mysoline). It was an effective treatment and the tremor disappeared, but it had annoying side effects. Are there nutritional supplements to treat my condition
