Welcome to the Forum!
I know that you are Type 1, but please read through the first three threads in the Type 2 Section, when you get a chance, if you have not already done so. These threads will most-likely help you a lot. Self education is one of the keys to successful management of your diabetes, along with a healthy / sensible diet and exercise. Basically, diabetes requires a life-style change for the better.
Blood Glucose Testing is very important to people with diabetes. This value determines the base amount of insulin needed, along with an additional amount of insulin to offset the carbs that we eat per meal. We call this total the meal bolus.
The
carb count for beer can vary (~6 carbs per 12 oz to ~20 carbs per 12 oz) by brand. I know that the European term for one beer is a pint, but I am not sure how many ounces that is. Here in the USA that would equate to 16 oz. In short, several of "your pints" would amount to several carbs. There is nothing wrong with drinking a couple of beers. However, you should always calculate the carbs and bolus for the carb intake.
There are normally not very many carbs in liquor. However, there can be several carbs in the mixers. The best mixers, for people with diabetes, are those containing very few carbs, such as diet soda or tonic water.
In summation, prolonged high blood glucose along with alcohol over indulgence and smoking will harm your body. Please work diligently to reduce your average blood glucose to below 140 mg/dl or 7.8 mmol/L, cut back on the alcohol consumption and learn to count carbs and bolus for your meals. You body will thank you down the road.
Test your blood glucose often. Good luck with your control and management.
