Opposite week

It seems to be opposite week chez my body. First I get back from a slothful and mildly gluttonous trip to new lows of weight and body fat. Then as I restrict to 1600 and exercise the next several days, it actually shoots up. When I go to bed at 10pm and have an alarm at 6, I'm tired and don't want to get up, but when I go to bed past midnight for the same wakeup time, I'm perky in the morning. At this rate, after my box of Annie's shells and cheese and several ice cream bars this afternoon, I'll wake up tomorrow light and feathery. I don't know, man.
