1) Two shots of vodka and you will be totally renewed. Just not more than that, because otherwise you are risking to get drunk again... And a good meal after that, of course.
2) Also in Russia we are used to cure handover by drinking cabbage brine. Some prefer a cucumber pickle, but it's less effective.
3) Or
Tan and
Kumis:
Choose the one which you prefer more
P.S. The 1st method is the most effective by a combine effect on your body. During the night you liver turns the booze into various toxins, including methanol. As you should know the best antidote to methanol is ethanol. So two shots of Vodka on the morning will help you to detox (sounds weird, but that's true). The second problem of hangover is headache, high body pressure and possible problems with heart (up to heard attack). That's because you are heaving a vasospasm. And here Vodka is also your rescue ranger, because it dilates blood vessels and relieves spasm. Plus to all of that it has a strong sedative effect. So "
similia similibus curantur"
