I went to a Neurologist and they did not run test other than the: hold your hands out, turn your head left, right, stay focused on object, etc., One doctor started me on primidone. The side effects were awful. I was vomiting uncontrollably and ended up in the emergency room after the second day. I changed doctors and the one I have gone to for the last 3 years told me to drink wine. At first he recommended red wine; however, I changed to white. If I'm having a 'bad' day, it helps. I take 6 oz. once a day and take about 4 days out of the week. I wish I didn't have this but there's not a cure at this time. My primary care physician is going to try something natural and new. The John Hopkins Uni. has been experimenting on the essential tremors. I'll let you know once I start (product) and then continue to update if I can tell a difference. I get embarrassed at times. We own a furniture store in WV, so I'm around the public a lot. Then to church on Sundays. So, seven days a week I feel awkward when it's a 'bad' day.
