At my last visit to the neurologist, I talked to him about what dose he would normally prescribe and he said 4.5mg. Aack! That's twice what I was taking, and I had noticed signs of problem behaviors developing. I told him I wanted to be on the lowest dose possible and he was sympathetic to that idea.
As soon as I got back to the Bay, I dropped my dose back to 1.875mg. I felt a return of some symptoms, but nothing bothersome. Eventually it settled down to the point where I was comfortable enough. My medication had stabilized!
