On the rare occasion that I have a drink, I have learned through trial and error that i need to have a cookie of something for every drink. I usually have a vodka and diet coke, or maybe a beer with my dad. Since there is sugar in alcohol, why does it LOWER my sugar? I have about 6-8 drinks spread out over a month. Sorry, forgot to add i m type 1 and on insulin 3 times a day! I am in control of my diabetes and have no problems when I have a drink on occasion now. I know what to do to regulate my sugar. I was just wondering what makes alcohol lower sugar levels.
