Headache, bronchitis, feature creep. But for years I've used light themes. Now I'm using dark themes and it's easier on my eyes. Hmm. Used to hurt my eyes to use dark! Anyway it's about the worst day to try this out because. ..just switched to clients text messages and the "know you're not feeling well but ..." burnt into my retinas bc i didn't think ahead to change any non IDE or dev related to a dark theme.
