When I was in Bangkok I slept for at least ten hours a night, probably due to the heat, humidity, jet-lag, and culture shock. When I returned to DC, I slept for most of the three day weekend, with MoBob occasionally poking me to see if I were still breathing or to wish me a happy Valentine's Day.
My body must now be habituated because I've been asleep by 7:30 or 8pm. I haven't changed anything else - still sedentary, still chugging at least three Diet Cokes a day, still taking the same meds. I'm not pregnant and I'm not depressed. I'm just addicted to sleep.
The downside is that I never see MB anymore. When I leave in the morning he's asleep and when he returns in the evening I'm out. So the only really "together" time is during that twilight zone when I'm drifting in and out and listening to the reassuring thump-thump of his heart.
