IRL drinking too much alcohol can have negative effects beyond getting drunk.
Any player that does not have much alcohol tolerance that drinks an extremely potent drink (e.g. vodka), in addition to nausea, they get Alcohol Poisoning, which functions like poison but slower acting.
However, unlike poisoned drink, alcohol poisoning is not lethal.
Short submission, but its one I think would be cool.
Yes, many people wish for more realistic mechanics for numerous aspects in the game. I bet Mevans is aware of that desite by now. May as well add 'rather obvious possible more realistic mechanics' to the WntS list ...
