I sleep from 6 to 7 hours daily. When I work a late shift (until midnight), its a 45 minute drive home, then wind down on my computer for an hour or so, then off to bed. By that time its 1:00 a.m. to 1:30 a.m. Sometimes I work day shift so I am able to get to bed about 11:00 p.m.
Take an hour nap when I can during the early afternoon (about noon).
