What was something you swore to hate forever, then did and actually enjoy it now?

Coffee.

For the first 45 years of my life, I found it disgusting. Then I finally had some “artsy” coffee that actually had a decent amount of cream and sugar in it to cut down on the bitterness and harshness.

I now joke about adding coffee to my cream and honey. It’s not quite that bad. But I drink a full half-litre of it (about 550-600ml after cream and honey) every morning now.
