First time I used Iosevka I felt really nauseated, kind of like getting motion sickness, it was a really bizarre experience for a font to give me. I was on a smaller screen though and getting some more characters in without getting tiny was actually a selling point, so I gave it another go and eventually got over the feeling.

Now (after ... gosh, 6, 7, 8? years probably) I love it, use it everywhere and other monospace font feels super w i d e and weird.
