I have been really thirsty for the last few weeks, drinking more than ususal. My daughter, who has type 1 diabetes, stopped by and we check my blood sugar level. This morning shortly after drinking a cup of coffee, with sugar and creamer, I registed at 396. So I waited 3 1/2 hour and retested..it was 347. Should I go to the emergency room or will I be ok to wait and see my doctor on Thursday?
