Your Sim will get hangovers the day after drinking. Your Sim will also get a few random additional buffs and moodlets dependant on how drunk your Sim is. The effects will be declining eventually if your Sim stops drinking. This is a gradual thing where the Sims will become more drunk the more they drink. Order drinks from bars like you normally would. Type in “bma_cheats” to access the cheat list. It doesn’t matter if you remove her Alcohol system or not, it will be blocked, unless you unblock it through cheats. As of version 5.0 this mod blocks KawaiiStacie’s Slice of Life drunk buffs.
