head of lettuce 

the feeling of being drunk again after your first alcoholic drink the day after a good long night of drinking. Like when you throw a head of lettuce that is wilting slightly into a bowl of water and it perks right back up, your drunk is wilting a little from sleeping and the first drink of the day perks it right back up!

"OH MY GOD! I got so drunk last night, this bloody mary is going to totally turn me into a head of lettuce!"

Having a head full of lettuce - to be extremely stoned.

"Dale, you can't smoke up before you shift!"

"It's cool, nothing makes me enjoy physical labor more than head full of lettuce."
