A bit unrelated, but try having l theanine after a night of drinking: it makes you wake up fresh and without a hangover because it speeds up alcohol processing and it metabolites by the liver and also prevents alcoholic liver damage. Me and all my friends who tried it say “i wake up totally fresh after theanine”. There’s also a study confirming this: https://pubmed.ncbi.nlm.nih.gov/16141543/
