Context: Last night , I fell asleep in the middle of Project Runway . I managed to put down my knitting mid row , but I was fully clothed and without a pillow or blanket . I only intended to close my eyes during a commercial but slept right through till morning . I did wake up with a blanket as my nocturnal vampires children discovered me and managed to cover me up after figuring out that I was still breathing but not budging . That 's how chemo plus two days seems to be going . Today , I was right as rain .
