TMI.... bathroom issues

hello • from ga. bi.

So ever since yesterday... I have had diarrhea. I literally can’t eat anything it goes straight thru me. I drank alcohol pretty heavily Friday & Saturday nights (we had people over). & I never drink that heavily. Yesterday I’m guessing it was the alcohol... but I STILL have it today & idk what’s going on. I don’t think it’s a stomach bug because I don’t feel sick or anything. Could it be from drinking so much?

Btw, sorry for the tmi.
