My son was diagnosed at 17yrs. He a school friend had decide to rent a apartment after he graduate. They were both working and I just new they would be moving back home. My sister who is a RN and visiting their new placed called me up and says you know Mel has been vomiting and we think he has gotten some bad fast food. I didn't  know that much about diabetes at the time myself and I just ask is there any thing else going on. My sister the RN states he is drinking a lot of water. I told her go ahead and take him to the hospital he is still cover under my insurance. He's level was up to 1000. They were shock he actual walked into the hospital. While he was going thru all the lessons and learning how to care for himself, his friend brought him a subway sandwich and Dr. Pepper because my son told him he was so hungry. His levels shot back up just as they had got them down, the nurse didn't know what happen.. He was very embarrassed about that.
