Not a lot of it...from 9:30pm-12:00am and 2:30am-4:00am and 5:00am-6:30am. Everything blends together. Hopefully I can take a nap today, even thought it is so gorgeously sunny outside. My mom use to take pictures of me sleeping up til I was a teenager. I used to sleep so deeply and now I feel on the edge of dreaming and waking all night long.
