Beer and wine are not the best choices and either are drinks with sweetened mixers but a Long Island Iced Tea would not hurt you other than getting you drunk so don't drink and drive.
I probably know a little more about this than I should "wink". I am a type 1 so I can only speak from that point of view. There is a definate drop that will happen if you drink like say a Shot of Liquor (usually 0 carbs). I am sure that some of the sweet ones may have carbs, so you can check. Good point to make here is that most Alcoholic beverages do not list nutritional Information. You have to look for it online. I usually stick to foods that I know the Nutrition on when I eat out so this is not a problem for me. I also have the iphone so i can look up at the resturaunt. I usually check my sugar before my first drink and usually order a light meal, no fries, nothing heavy carbs, like a sandwiche with a light protein (chicken etc., no beef). So i go ahead an bolus for my dinner and my first drink (if there are carbs). A light beer works best for me i think they usually have 7-10 carbs per beer. After my meal I do not usually bolus for light beer. I check my sugar after an 1 or so (more time after the meal is better you want 2 hours) then I make a correct if needed, but I usually back off a little to 1/2 the correction. When I am done my goal is to have my sugar in the 200 range two hours after my last drink. any lower I typically will have a drop in BG. That is my light beer calculation, the calculation for each drink is different. If I am drinking liquor I try to stay away from the carb ones, no flavor rum, vodka, wiskey, I usually don't drink liquor so I can't really give you any advice. I like to have beers. Another note, if I check my sugar after my meal and it is low, then I will have non-light beer or a mixed drink with a full flavor soda etc. I met someone on time that was wearing a pump and she owned a bar and she would drink a lot. She would end up in the hospital with low sugar and she continued to do the same thing over and over. She had no idea why her sugar would drop, i would not recommend that you drink if your not willing or able to control your BG. I would start by drinking the same thing until you figure out your body. There is no set formula for anyone.
