I'm a restless person so it's hard for me to calm down and relax after a hard game (I try to change the situation drastically.I have a friend who loves fishing and if he is free, then I call him and we go fishing, but this is rare. I just go and buy myself something delicious, (I like dried and salted fish or cake for example) and call my friends to tell them about my game and experiences. But if the game was especially stressful, I can drink beer to relax, Especially when I'm going to tilt. Then I regret it.) I also do not advise you to drink)
Sometimes I go to the movies with friends after a difficult game, in any case, find a person with whom you digress from poker, do something fun!
