No, worse stuff like comas happen usually happen with meds I think, take too much insulin and not enough food, blood sugar drops too low. i've had that happen with oral meds, what a rush, man! but no, people can go a long time without knowing. type II, it just danages your blood vessels, if you had type I you'd be getting skinny. anyway i'm glad you're going to the doctor soon they should check it. ontheother hand could be your meds?
