I'm another one who saves calories for a night out.
I'll try and save calories where possible, fit in my biking early, and choose the food I'm eating well. There are some days where alcohol calories are worth it to me and some days where they aren't, so I go with how I feel at that point and let that guide me as to how much I'll be drinking.
I also just want to say that while I do go out once or twice a week, I do like to have some alcohol free nights out occasionally, so that's always an option if you feel like giving your liver a rest like I do.
