If your pee tastes sweet whatsoever, it's the indicator for a diagnosis as they did it in the old days. Alternatively, leave a glass of your pee outside and if any sweets-enjoying bugs or ants get in it, it may be sweet and you'd be a type 2 diabetic. If you believe you're type 1, you need insulin or you'll die, don't eat any carbohydrates in the meantime.
