reverse hangover 

Had a big night on the raspberry cordials. To your dismay you wake up the next morning feeling pretty good but for every hour your awake you feel considerably worse, until you eventually feel as hungover as you should if not worse.

Mate: I woke up this morning feeling fine considering how drunk I was last night, but I went to get some food and it just hit me like a bus.
Me: Haha, you did grab the bouncer on the butt on the way out of the club!
Mate : I think I've got a reverse hangover.
