Unless there are medical reasons why you should completely avoid alcohol, you can still enjoy a drink!
Beers, ciders, lagers, liqueuers, fortfied wines, mulled wine, stout, white wines, rosé wines, sparkling wines and champagne all contain either traces of or a certain amount of carbohydrate that you would have to think about accounting for if you want to drink more than just an odd glass.
Red wine contains no carbohydrate and spirits (gin, brandy, rum, vodka, whisky) contain just negligible traces - but if you mix spirits with orange juice or non-diet soft drinks, you’ll have to account for this accordingly.
Overindulging in alcohol (getting paralytically drunk!) can lower you BG and if you do get dangerously drunk this can mask the symptoms of a hypo and put you in a difficult situation, especially if you’re out on the town with friends and where lots of people have had quite a bit to drink and your hypo is interpreted as just drunkenness.
Mixing drinks and drinking on an empty stomach is not recommended for anyone.
Because you’re recently diagnosed, you might want to think about going to a bookstore and getting a food and diet counter book. These books are generally cheap and they list nutritional information for foodstuffs and drinks. They’re really useful to have. I refer to mine quite a lot.
