I agree that everyone is different. I also want to be clear that binge drinking is not healthy nor safe for anyone, particularly diabetics. However, we can enjoy alcoholic beverages, in moderation, with some planning, experience, and education.
I recently got my first CGM, and it has made enjoying the finer things in life (alcohol, pizza, ice cream) more enjoyable. Although initially I get constant feedback from the CGM telling me my BG is too high, it helps be manage the situation better on the next attempt. And even better, I no longer feel deprived of foods or drinks that are “off limits”.
But, this is about alcohol. Here are the results of my personal experiments, and the tips/tricks I have developed to manage enjoying adult beverages with less anxiety:
I have found that (in moderation) alcoholic drinks that have 10-15g carbs or less per serving do not disrupt my BG drastically. If I have wine (~5g carbs/serving approximately), light beer (~5g carbs/serving), or liquor drinks without additional carbs, in excess (>3 in a day/night) i will experience a drop in my BG within the next few hours AND I am more likely to drop over the next 24 HOURS.
I manage by 1) eating before/during drinking 2) not bolus-ing for the carbs and sticking to lower-carb options 3) snacking before I fall asleep 4) occasionally decreasing my basal insulin the next day, and last but not least - CHECKING MY CGM EARLY AND OFTEN. I also aim to fall asleep with a higher target BG than usual (150-200) and setting my CGM low alert a little higher (90 instead of 80) than usual in case I do start to drop while i am drinking or in my sleep. Also, I am never drinking alone. I am always with a friend who knows what to do in an emergency, should one happen despite all my careful planning/preparation.
I definitely recommend testing one drink at a time, and watching what happens to your BG either with hourly finger sticks, or even better, on the CGM. That way, you can better understand how your body reacts and you can develop your own strategies.
