Hi.. I am 62 and was diagnosed 4 years ago with fine tremors on left side, stiffness and slowness to the point of almost a full stop. So now it's 4 years later and I've had to quit work a job I felt very passionate about. I'm driving very little now only short distances and when I feel I'm on my meds. I am taking Sinemet 100/25 2-3 tabs every 3 hrs. I usually get about an hour "on" time. I've noticed lately a telltale sign that med wearing off is blurred vision..I've told my neurologist but of course she says she hasn't heard of this so its not related? Just wondered if any one else has had this ?
