With this mod, Sims that aren't gluttons will stop eating as soon as they are fed up - just like it was in the Sims 2. I recommend to use the grandmeal module in combination with my moregrandmeals_tradionstweak. Otherwise, your Sims will not fulfill the grand meal tradition when they don't finish their plates.
This mod changes the autonomous coughing interaction that Sims are doing in industrial neighborhoods in a way that only Sims with certain traits will be affected, while all other Sims just won't care.
