Up at 7 weekdays so I go to bed between 10.30 and 11.30 PM. So that's about eight and a half hours. But being an old fart I often wake up once in the night needing a widdle, so then it takes me ten minutes or so to go back to sleep. Wake up more than once in the night and i'm wrecked. Sometimes my cats wake me up [I have 3 ] and want to go out, although not too often. Weekends, unless there is something really fantastic I want to catch up on on via the iplayer [need to get my TV fixed] I usually go to bed around 11.30. Saturday and Sunday mornings if I wake up I always go back to sleep. Often I will have some breakfast and then go back to bed for a couple of hours. Pull the phone out and just wake up naturally [or when either my son or the cats wake me up,LOL]. A few weeks ago one weekend I woke up ,after going back to bed again, at four o'clock in the afternoon !!
