I'm not sure there's anything I avoid purely because of hangovers or memories Just stuff I won't drink again because it's fucking disgusting, like Haig Club (screw you David Beckham)
Worst ever hangover was just white wine, but I was 16. I didn’t touch it for about 6 years after as the smell would make me sick. Anything since has never put me off the specific drink.
Southern Comfort and Ginger Beer. I tore through an entire bottle in about 45 minutes and then was sick out my window in halls. The guy downstairs came to check on me the next morning to see if I was ok, after cleaning my sick off his window. I died of shame.
Kylie's Merlot. Not because of a hangover, I only managed a glass, just thought it was disgusting. Will happily buy her other two wines again though.
Have had a bad experience with gin (was at a gig and thought gin + coke was a good idea for some reason) and don't particularly like the taste so avoid that.
Tequila, southern comfort and malibu tend to be my go-to spirits these days
