As Drunk and Hangover inflict status penalties akin to several injuries, it would be fair to display information in tooltip about the duration necessary to recover from it, like all injuries have.
Long story short, somethink like this:
– Before
– After
Also, Drunk status shouldn’t last longer than a day, unless the character is incurable alcoholic and his liver is completely useless.
Especially in a world where severe crippling injuries heal in mere days, one week at most.
