Not all drinks have alot of carbs. Regular Beer is high in carbs. Light Beers are lower. Most hard liquors (Rum, Vodka, etc...) are virtually carb-free. Alcohol will stop fat burning...but, only as long as there is alcohol in your system. Once you are sober, you start burning fat again. I just looked at your stats (155/155/155)...and it appears you aren't on this for weight loss...So, I wqouldn't worry about ketosis. Just keep your carbs at as level where you neither gain nor lose and you should be fine.
