I have constant shaking at night or when I sit in recliner, like a motor running and shaking all night long. My right hand shakes during the day at work. I have no problems with balance or sense of smell, No pain or headaches, no vision problems, no urinary or bowels problems, no fever, I drink 1-2 cups of weak coffee per day, social alcohol once or twice a month, I take blood pressure pills, natures thyroid for slightly low thyroid but still in normal range. I take vitamins and minerals.
