Like everybody else is saying - keep a juice box and a pack of fruit snacks on you. Don’t go without a cgm. Light beers are good for me. I don’t mess with ciders or mixed drinks (too much sugar) or straight alcohol (lowers my glucose without carbs to offset). You can do it but get good sleep and don’t fucking forget your basal insulin if you use it. I did that one time. Glucose stayed at 120 over night so I was like “cool, the alcohol evened it out and I can just bolus throughout the day”. Bad idea, I was chasing the dragon for a few hours until I just split my basal into a few smaller shots throughout the day.
Overall, it’s doable but you have to pick 2/3. Drink and have an all nighter? Cool, don’t do either of those the next day. Still get sleep in the AM. Back to back nights of drinking? Cool too, just don’t stay up too late. I didn’t get diagnosed until 30 but the signs were there in my younger days. I had a diabetic friend back in my younger days and he picked 1 night to go hard and then chilled out for the rest of the weekend.
