Drank half a fifth of vodka Saturday night & woke up the next morning violently puking

I rarely drink & I’m 145 lbs. the next morning was absolute hell. Couldn’t keep water down, constant nausea, for about 3-4 hours. Well I’m pretty sure the stomach acid and bile I was throwing up as well scorched my throat. It doesn’t hurt unless I take a few bites of solid food. Yesterday I was able to drink a smoothy & today I thought I was in the clear so I went & got some hibachi chicken & about 5 bites in my throat starts to hurting very badly to where I just can’t eat anymore. How long will it take for the protective lining around my throat to come back? Is there anything I can’t drink or eat that will help? What if it’s irreversible!?
