Stomach issues for 2 weeks now

Well long story short about 2 weeks ago(exactly now) I drank a lot of alcohol at a bar with friends. I thought something was odd that while my headache and pains went away but not my stomach issues. I've had diarrhea and just runny stools for a while now. I also had a feeling of being full and couldn't eat big meals at first but that's gone now I think. I had a stomach ache about 4 days that was bad, but that was only one day. It seems like eating the wrong things can make my stomach hurt a little, but I do know these issues shouldn't last this long. Guess I don't have alcohol poisoning, but maybe I messed up my stomach. Anyone have any long lasting stomach problems after drinking to much alcohol?

Does prune juice make stools runny? I’ve been trying to eat veggies and stuff to make my stomach better. I still cant get any large stools, they all come out runny.

My stomach also only hurts now when I sit and lean forward. Well it hurts more so below my abs. Sigh all this stuff only happened after I drank to much alcohol that night.
