A hangover is nothing but dehydration and acid digestion. When you get lost in the desert next time and get dehydrated, you will experience a hang over. Alcohol is a diuretic, an effective one.

"Nooooooooo, it doesn't", says the panel of unethical morons. I would love to test the reaction of the ad authority if we made the same ad using middle aged (50-60) City bankers and business people, scantly dressed in equivalent clothing (underwear, trousers and shoes on hand).

Hopefully, it would last more then 20 minutes, no matter how much booze has been ingested by the parties involved.
