I like the whole thing of having a drink or two w/o actually being plastered. Since there is numbers already involved in the drunk code here is a possible suggestion to make it a bit more fun.
Drink lvls:
Mugs of... = 3pts
Wine = 4pts
Shots = 6pts.
Drunkeness meter = con + 5
1/3 of drunkeness = buzzed
Code:
You feel slightly buzzed
1/2 of drunkenness = drunk with 50% chance of slurred speech.
Code:
You feel drunk and you notice your speech slurring.
3/4 of drunkenness = smashed with 100% chance of slurred speech.
Code:
You have a hard time concentrating through the drunkenness
1 of drunkenness = passes out for 1 ic hr. then moves drunkenness to 90%.
Code:
You pass out drunk [what you see]
Passes out drunk [what everyone else sees]
You lose pts of drunkenness = Con/5 + 1 pts/2 IC hrs.
