Alcohol is EVENTUALLY broken down into sugar. It often initially lowers the blood sugar, by supressing the activity in the liver that converts it to its component sugar. But if you have a well-functioning liver, it will break down the alcohol, and raise your sugar, like any other carb. I'm T1, and always run high BGs the day after I've had any type of alcohol (usually, when I do, it's a glass of wine...rarely!) You either have insulin resistance or you don't. Most T2s are in fact, insulin resistant.
The above link gives the party line about alcohol with diabetes. Like most things, it is never wise to overindulge. Be careful, OK?
Have a happy holiday! HUGS! sheryl
