@emmys - a discussion of carbidopa/levodopa (Crexont) all by itself would be a really good one, if you'd be willing to start it. You'd go to the home page for the Mayo Clinic Connect Parkinson's Disease support group, https://connect.mayoclinic.org/group/parkinsons-disease/, and scroll down to just under the blue box on the left side to click on "Start a new discussion."
