This mod prevent sims from drinking water autonomously. I dont actually know why this interaction is a thing in the game, but sims perform it very often. With this mod your sims will not get water unless you direct them to do it. This is really helpful because sometimes they stop other interactions to do it.
Side Note: If you hate sims doing push ups, sit ups or stretching everywhere, I recommend you getting my No More Push Ups and Sit Ups Mod too.
Happy Simming!!!
