the most important thing to know about booze is that, in its purest form it lowers the blood sugar, due to livers normal output of glucose being disrupted as the liver tries to expel the booze..........
so in the first instance, being aware of what you have had to drink before you sleep that night is important, as well as getting into a routine of eating carbs uncovered by bolus/quick acting insulin and/or reducing your background insulin. Drinking is a good example of when a split basal dose would be handy....
not all alcohol comes as spirit, so there may be some that come with carbs in them like beer, cider, vodka mixers............all of these can be bolused for if you are familiar with the effect the booze has on you.............for example, I could have 3 pints of lager, take a bolus, 10g per pint, go home and not worry about reduced basal or carbs, having more than this amount of booze will effect my liver and therefore I will need carb/basal reduction.....
so its all trial and error, have fun doing it, but be extra careful and take care.......
