Check this. Korean researchers have discovered a way to create alcoholic drinks that reduce hangovers without weakening the drink. How? By adding oxygen bubbles to the liquor
When you drink ethanol, you body needs to oxidize it to water and carbon dioxide in order to process it. This occurs via hepatic oxidation, where the liver does its thing to counteract the liquor you’ve just poured down your gullet. The enzymes that process alcohol require oxygen to function, and it’s thought that by storing the oxygen in the alcohol itself, the system functions more quickly and efficiently.
