I am on Rytary 36.25/145, 11 per day, which is similar to sinemet cr4, a timed released version of sinemet. Regular sinemet made life dangerous for me. I would fall asleep too quickly while driving with regular sinemet. As for DBI, that is new to me, but all the medical terms are ganging up on me. I keep thinking that dimentia is right around the corner for me. OTOH, some of my "normal" friends, aka my "control group", act just as loopy, so......
I will share your info with my new neurologist, a young guy, who just started his practice in Logan, Utah. Before he got here, I was driving 90 miles to and from SLC, often in heavy traffic, to see a different VA doctor much of the time.
