I stay up until about 4:30 a.m. and sleep until 11. I learned to do this because my daughter and her 3 kids with ADHD lived with me and the only me time I got was after they went to bed! So, so peaceful!!!!!!!!!! Now they've moved but I see no reason to change my schedule. I even insisted on a daytime nurse to take care of my foster son so that I could sleep in. I also don't make appointments before 12:30 in the afternoon--later if possible. ;)
