I have the same story. After fun parties, a hangover can really linger for several days, and this is quite unpleasant. What usually helps me is to drink a lot of water and eat something nutritious, like broth or bananas. I also try to rest and, if necessary, take vitamins and headache medications. Friends advised me to turn to Las Vegas IV https://pushiv.com/ in such cases, but I have not tried it yet. Try doing the same, maybe it will help you cope better with hangovers after fun!
