If you're not in contest prep, or if you're in the early stages (subject to your progress) of prep where you still have a cheat meal scheduled, I would say, if you "need" to have a drink, then put it on your scheduled cheat day. A "good" diet / lifestyle can absorb that sort of "once / week" type "cheat". I'd even go to the point of it's just good practice to "throw some shit down the piehole" (technical terminology) to exercise your system. I find I become lactose intolerant and generally more limited in my ability to process things when I've been on a very strict (variety-wise) diet. But as mentioned above - moderation in everything.
If you research the cals of various liquors - the "white" or "clear" ones are the lowest (least amount of sugar, e.g. compared to like spiced rums, etc.). I found these types of liquors are even "on" the keto diet (where carbs matter). One of my first trainers suggested Vodka / Cranberry - vodka is ultra "clean" / low cal and cranberry is a good antioxidant & good for your liver. But if you want to avoid the sugar in the cran juice, there's always any other zero cal mixer - soda water, diet coke, Crystal Lite, etc. Of course you then get into the consideration of what fake sugar does to your system, but hey ... the point is to not restrict yourself to DIE w/ T, but rather a lifestyle that supports the goals you want.
If you're in contest prep, then set your priorities accordingly. There's always at least one other person on stage day who was "more dedicated than you" if you're struggling w/ the urge to let it all go.
