I have this theory that 8 or so hours of being horizontal allows everything to resettle into the most attractive package possible. After 14 hours of sitting, standing, eating, and jostling, the fat packets have shifted downward, resulting in the bulgiest bulges and clumpiest clumps of dumpiness.
Test this theory o' mine out--before going to bed, give yourself the once over. Note the lumps and rolls. Then, as soon as possible after waking, give it another look. See if things look slightly smoother to you. And then work with that image.
