I have started doing some tests to determine, to the extent possible,
What I found is that the Sinamet seemed to be only slightly effective. By 3 am, I was still careening around, from one support to the next. It didn't get much better if any when I added the Mirapex, and even the other meds had not done much by the tie I left.
So I wasn't expecting much this time. But right on schedule about an hour after the last med (the steroid) was taken at 7:30, I was able to balance standing up and walk with a normal gait. This occurred once I had reached Trader Joe's. As I got off the bike, I could feel that my "balance system" was back in action.
The ride ended up as a very successful one. By the time I got back home I was fully "on," with no balance problems whatsoever. This state has persisted until now, about 2:30 pm, and I hope it lasts much longer.
When I got back home, I set up the video camera on a tripod to get some movies to document how my motor skills are doing. So with no further ado, let me present the film "After the Bike Ride":
