Well I don't know if I can say I'm making it work. I do end up in some crazy situations, like during winter not seeing daylight for a few weeks. I still think of it as being in "Well, that can't be good" territory. Then there's the horror of thinking - "If my work situation falls apart and I have to get a 9-to-5, how will I even deal with that?".
I sometimes wonder if it'd just sort itself out if I quit caffeine completely, and stopped staring at a screen all day... but that's not exactly compatible with my career.
