I can help. This is a quick overview of diabetes and medications etc.
Type 1 is when your pancreas produces no insulin. You need insulin injections to live.
Type 2 is 'insulin resistance'. Your pancreas produces insulin, but the cells are resistant to it.
Typically with Type 2, two medications are used, Metformin which helps the cells take in insulin (lowers resistance) and Gilclazide, which causes the pancreas to secrete more insulin. There are others but they are the main stay. Sometimes, when the maximum safe dose of the above drugs is reached, it is necessary for a Type 2 person to go onto insulin as the resistance has become too great.
People on insulin typically take 2 types of insulin, long lasting and short acting. Most Type 2 can go with the long lasting alone as it does for 24 hours, but some have to take the short acting too with meals. Type 1 will have to take both.
When starting on insulin regimens, there is always a sort out period to see what you need, but typically with short acting, it is easy to count your carb units and give yourself the appropriate dose. The long lasting of course is a 24 hour dose. If you don't eat enough, skip a meal, forget, it is possible on long lasting insulin that there is enough of it around to keep your blood sugar at a dangerously low limit. The one thing with diabetes, type 1 or 2 is to be consistent.
It is quite unusual for a type 2 person to experience hypos, if he is he is taking too much long lasting, or not eating enough.
It is easily handled but takes a bit of discipline, but your first aid was good. We have orange juice in our hypo kits, as well as glucose tablets. First aid for hypos is a fast acting sugar, orange juice, coke, fanta (shit loads of sugar in fanta) but remember not the diet versions, followed by something like a sandwich.
Until you are sorted out a 0200 blood sugar check is really a good idea, since it is then that sugars hit a high, but yeah, regular eating and watching the booze.
Any more questions, ask away.
