I'm sort of a newcomer - non-medicated diabetic. When I make that big mistake about diet and get a high blood suger (180-220) -very rarely,I might add- I experience fatigue. But then the next day, I feel lousy too.
Am I perceiving this correctly or is it all in my mind? Please help

Sure sounds like it to me .I get the same way ,so i make sure Im not going to eat too many simple carbs . You gotta watch it .It will get you in the end. Unhappily I just started meds today . take care mizzy
