i find as long as you're not taking any orals, you should be more or less ok
even on dbol i'd drink sometimes, but the shitty feeling afterwards the next morning was definitely much more noticeable than without the dbol. i try to avoid that now, if at all possible
try to get in as much antioxidants as possible, that always helps me recover after a night of drinking, and proper electrolytes too as others have mentioned. there's that pomegranate juice you can get in the health section of grocery stores that helps, also another thing is get some tea that is high in antioxidants and just boil a whole gallon of water and steep a bunch of tea bags in it, it will help flush all the toxins out and tastes good too.
another thing i like is get unsweetened dark chocolate powder and make a really strong mug of cocoa. crazy high in antioxidants and no carbs/very little cals
liquid based tomato foods like tomato juice and tomato soup work wonders as well, studies show these have more antioxidants than solid tomato foods. but the solid foods have more lycopene which is a cancer-preventative substance so eat tomatoes as well
