To: J.R. Bruman From: Will A. Kuipers Joe, Your response to William A. Parrette makes me think about my own experience with tremor. I cannot quite agree with your theory that exercise would deplete the amount of "free" dopamine and so cause "end-of-dose" symptoms. In my case the increased tremor occurs upon exercise, or any kind of stress, or excitement, or even just a lowering of the temperature. All that is necessary is to take away any of these causes and I will be as before. I see no need to correct the condition by some small addition to the routine dosage. I am on Sinemet CR 50/200, 2 1/2 per day. I have been on this for more than seven years. Will Will A. Kuipers Dallas, Texas 78 / 71 / 70 <[log in to unmask]
