So I got blackout drunk once and now I puke even at the smell of alcohol.

Long story short, I drank too much Glenfiddich whiskey one night, threw up all over the place and got blackout drunk. A week or so later I tried to drink whiskey and I threw up after just smelling it. Now I can’t drink whiskey or cognac or anything similar, my throat just automatically closes and I end up puking. What’s happening and how to cure this?

P.S. I have tried vodka and it’s fine if I dilute it with juice and stuff but I can’t drink vodka shots either.
