Funny thing about brain chemistry problems: it seems un-effing-possible to get other people to understand what it's like. I'm sunlight-addicted too (in Southern California, so it's not too bad....), and I'll get the "Pull yourself together, stop being an insomniac / oversleeper /whatever" comments too. It's not like that. For instance, if you're a coffee drinker and one morning there's no coffee in the house, you are simply not going to feel sunny about it. There's no point saying, "Oh, just don't have a headache." Coffee alters brain chemistry, and that's what it feels like. Obviously, Tom does all the pulling together anybody can do. 10 (or was it 12) hour shifts, writing a blog, writing books, and rising so high in WOW he has bananas on his shoulders. What more do you want?
