Greetings,
As a 26 year Type 1 diabetic, using an insulin pump for the last ten years, I feel I can speak from some experience.
First and foremost, a 462 BG reading is flat out dangerous. If your BG is that high for a long period of time, DKA (Diabetic Keto-Acidosis)can result. Ketones and acetone are by-products of severe fat and muscle metabolization because your body lacks enough insulin to metabolize sugarinto energy.The kidneys can only flush so much out of the body, but eventually are overwhelmed. The ketones, acetone, and sugar build up to toxic levels.
A normal (non-dibetic) person can eat copious amounts of carbs (sugar, soda, candy, etc.) and never, ever have a BG over aprox. 120 mgdl. Sorry to say, a 462 after eating a baked potato, means you ARE DIABETIC! No question. You definitely need to see your doctor IMMEDIATELY, if not sooner.
I feel for you, as I was in denial for a period of time after I was diagnosed. Taking shots was something foriegn and scary. I didn't want to believe it, but facts are facts.
But trust me, after time, it all becomes old hat and routine. It's just a different lifestyle. My suggestion, take it or leave it, is to accept it, and dive into the diabetic lifestyle with both feet. See your doc and a nutritionist. You'll feel a lot better, I guarantee!
As far as pipe smoking and diabetes, I've personally noticed no difference controlling blood sugars nor any ill effects.
Good luck!
