I have quite a bit of experience in the subject. I avoid sugary drinks like virtually all mixed drinks unless mixed with sugar free mixers. Lite beer is manageable due to its minimal carbs, red wine is a non issue for carbs for me, I don’t bolus for it, it actually lowers my blood sugar and stabilizes it if anything…
The main risk of alchohol specific to type 1 is that it can affect your blood sugar, and your ability to recognize problems with your blood sugar… but in moderation, if you know how it affects your sugars, it’s fine
