Ok first off happy birthday!! And second i was a Type 1 diabetic for about 6 months when i turned 21 and i have been on a rugby team all through college and collegiate rugby=drinking...alot lol, so here are some tips i have found.
1. I love beer, especially dark beer (guinness is my favorite) but beer will raise your blood sugar due to the ingredients, but the darker the beer the more it will rise. But stuff like Bud Light, Michelob Ultra, Miller Lite, etc. doesnt really affect it too much until you start getting into 6+ beers range.
2. If a liquor is flavored or has color its going to also raise your blood sugar to a point, especially if mixed. A shot is not really going to do anything, but a Jack and Coke.....say no lol. I have found though that Jack and Coke Zero taste the same and really wont do much damage. Just avoid juices mixed with the liquors.
3. Last point, clear liquors like vodka and everclear are your friends. If i do drink liquor its vanilla vodka and coke zero. It doesnt affect my blood sugar, i get drunk, and it tastes great. But just watch what you mix it with.
Anytime you drink you have to watch your blood sugar, just have a close friend be your diabetes watcher for the night that will check your blood sugar for you and take care of you so you can enjoy your night, just make sure they know what to do at all times. Hope this helps
