Alcohol overdose help?

So I drank a glass of straight tequila last night. Didn't really eat anything before it. I think it was like 250 mL. I woke up with vommit and pee in my bed (okay that's kinda funny I know) but like I felt terrible all day like pretty nauseous and just like death like there was actually pain in my stomach. I was super slow and out of it. Could still think just fine. 24 hours later, I feel a little better but still kinda dizzy and woozy/slow. I feel nauseous sometimes too. I'm scared that I did some serious damage or something permanent. I just want to go back to feeling normal. Had like four or five bottles of water, burger and fries, toast, and chips today. Hoping someone can give some insight and advice on how to fix this, yes I know it was a stupid thing to do and I have learned my lesson. Please and thanks
