i have type 1 diabetes, please tell me why this happened....? about a month ago i took a trip to florida and the first night i was there i had a low blood sugar. i drank a can of mountain dew, and my blood sugar still didnt come up after 20 minutes...so i drank another one and it STILL didnt go up...my dad then went to wallgreens and asked the pharmasist what to do (the pharmacist also had type 1) he said to drink orange juice, so thats what i did and my blood sugar went back up to where its suppose to be.  why did orange juice work and pop didnt? pop usually brings my blood sugar back up 90% of the time.....WHY NOT THIS ONE TIME? did it have to do with stress from the trip or what?

Summarized question: Could anyone provide more information on the cause of type 1 diabetes?
