Mages can summon food and water. Ask them for some! =]

You cannot eat or drink while in combat. You are considered "in-combat" if any nearby monster is engaged with you.
Food and Drink are in separate categories, so you can only have one food effect and one drink effect on you at a time. The only effect should be that foods that used to stack with each other (you could have two food effects on you at once) no longer will stack.

Drunkenness

Your character can become drunk when drinking too much alcohol.

If you become more than 50% drunk, you will have drunk bubbles hiccoughing up occasionally.

As you get more drunk, you start weaving when you walk.

As you get more drunk, you start slurring your words in chat.

Every 20% drunk you are, creatures appear one level lower than they actually are.

Drunkenness is saved when you log out and fades over 15 minutes.
