Oooh, I know what you mean about getting obsessive with hobbies or just generally loosing track of time. It's five o'clock, I think "I can read a chapter or two before I go buy food for dinner." Next time I look up it's nearly midnight and only the local 24hr convenience store is open. It's not *my* fault reading is so fun! Though in your case I suppose it would be writing? In Orochi's case it's science and that's a bit worrying in case he passes out mid-experiment and things go boom.
Yeah, this is totally what I do with writing. Glad to know I’m not alone. xP
