Dizzy Gazelle was chosen by me because:
1) I've been dealing with vertigo and unsteadiness for a while now, with no relief yet in sight, and
2) gazelle are graceful, beautiful, and are very capable on those legs of theirs, all things which I envy and long for.
Beyond that, other names are variations of Dizzy, like my current one, Dizzylis, which is merely a portmanteau of Dizzy and Chryslis. Chrysalis is my fav MLP character. Love my Chryssy.
