I am a Type 1 diabetic and have been since I was 13. When I was first diagnosed I'd probably been suffering with it for a few months but I'd gone right down to 6 1/2 stone, I was skin and bones. Diabulemia is an eating disorder, much like anorexia/bullemia and I actually know a diabetic girl who suffered with this condition. Basically if you do it your blood sugars will run extremely high and you may damage your nerves/eyes etc so it's not a wise decision. If you even mention stopping taking your insulin for a day, let alone a week, to a Diabetic Doctor he'd probably string you up!! Serio
