in the comments on « History of Russia » G. Leklerka. - For this, different means are used: some, having drunk a bowl of vodka,
satisfies the pain. Other refresh themselves with soft drinks, that is, they drink sours, lemonade, lingonberry water, cucumber
pickle. The best way, in my opinion, is not to have a hangover, never to get drunk "
HAPPY HANGOVER !!
