Getting up, taking a cold shower, going to bed

This is the hammer against hangover.

If you wake up and do not just vomit, but only have to deal with headaches and general malaise, then take a shower. First warm, then lukewarm and then cold.

Your body is shocked and no longer thinks of headaches or hangovers. Emergency function on, hangover off. Your eyes will open in fear. In any case, leave the shower with cold water as the last wash.

After that, you will have mobilized some vitality that will allow you to quickly eat or drink.

Then back to bed, darken the room and chill out.

My perfect remedy.
