I’ve had T1D for 14 years and recently turned 21. Alcohol definitely does some weird things to my blood sugars, but I had to do trial and error to really figure out what worked for my body. One way I drink safely is by being in a group where at least one person will know what to do if my blood sugar gets dangerously low or high. Also, when I was still figuring out what my blood sugars would do, I would only have a couple of drinks at a time and not go too hard on drinking.
I’m part of the College Diabetes Network chapter on my campus and it’s a group of people with diabetes. We all get together and talk about diabetes and college and the various challenges we face. CDN has a page just for info on alcohol and diabetes. If you’re interested here is the link: https://collegediabetesnetwork.org/content/touchy-topics#alcohal
Overall, CDN has some really awesome resources that helped me answer some of these tough questions about diabetes and college life. I hope this helps!
