my stomach/digestive system has been destroyed since getting drunk, advice on how to fix?

basically last Tuesday i got hammered, it was the second time ive ever been that drunk, im incredibly lightweight and was drinking straight vodka at some point. sorry for tmi but ive had really bad shits since then and despite drinking electrolytes, healthy foods and regularly, it doesn’t seem to be improving. i thought it would have gone away with the hangover but here i am on the saturday, on the toilet wondering if i burned my intestines away.

does anyone else experience this and how do they make it go away, i have a trip planned tomorrow and monday so im a little worried lol, thanks!
