I am a 55-year-old woman diagnosed with essential tremor. The tremors can get quite severe. Am on Propranolol 60 mg q.a.m. and 60 q.p.m. I was up to 80 q.a.m. and q.p.m. but could not tolerate it due to heart rate dropping down to 39 at night. Back at 60 mg 2 x daily. I am also on Ambien 10 mg at night for sleep problems. When I take them around 8 or 9 pm, I notice a great reduction in tremors. Why can t I take Ambien 2 times a day for the tremors? I do not work and do not drive. Only other medical problem I have is migraine. Am seeing a neurologist every 3 months for tremor and migraine.
