Hi, Drinking can get quite complicated with diabetes. I'm type 1 too. Be prepared for a few ups and downs, still after 17 odd year I sometimes get it wrong on a night out.
The main advice I would give is always back up your alcoholic drinks with some carbohydrate as alcohol can significantly lower bloody sugars. Most of the time they will spike because of the sugar content of alcopops/beer etc however, hours later, often during sleep you can have a nasty night hypo.
I usually have a big tea with a few extra carbs before I go out, I only give the insulin for the main meal, not the extra carbs i.e bread /small chocolate bar/biscuit or fruit.
Stay safe, carry extra glucose tablets/sweets with you and if you can keep an eye on your sugar levels whilst your dancing the night away :lol:
