As a Type I Diabetic for 30 years, and a user of the medicines you cite in connection w/PD for the past 4!/2, I can only testify that I've noticed no correlation between my blood sugars (tested 4Xdaily) and any PD drug (sinemet, tasmar, comtan, mirapex, selegiline in varied doses and amounts througout that period).
