Remember that I'd reached 77kg about a month ago? I've lost another kilo since then, without even trying. There's nothing like pervasive stress and lack of sleep to make you lose weight, I guess. Not that I lack appetite, mind you - I'm plenty hungry at dinner time - but I feel full as soon as I start eating.
Anyway, this is just a temporary problem. Tomorrow is my second vacation day of the year. Ritsuko is going to Tokyo even as I write, and after work tonight I will take the train and join her for a long weekend in the capital. We'll go see a big outdoor temple market in Asakusa, spend an afternoon in Jimbocho (home to hundreds of specialist used book sellers), have Smörgåsbord at a Swedish restaurant and probably spend Sunday in nearby Yokohama and its large, lively Chinatown.
I strongly suspect I'll gain back the weight I've lost, and then some, by the time we come back.
