A recent habit of mine is to wake up late on Sunday (maybe 2pm?). Skip sleep on Sunday night - and then crash into bed early after work on Monday evening (around 7pm).
It kinda' works for me. It feels like I get to extend the weekend by an extra night. And by the time I am feeling good again (and back in sync with the rest of the world) - it is Tuesday evening. So - it feels like you skip through the first couple of days of the work week. And it means I get to have a nice 10 hour sleep on Monday night.
Also there is nothing more enjoyable than going to bed exhausted - and knowing you can sleep as long as you want. It feels better than sex - and it is realy fun knowing you will be in a deep sleep within a minute of hitting the pillow.
And I hate forcing myself to sleep when I am wide awake. Particularly since it usually results in poor quality sleep as you are constantly aware of the hours slipping by before you have to wake up. So - the above takes care of that as well.
The only down side is I get very sleepy between 11am and 1pm on the Monday. But then again - I am often sleepy at work anyway. So - it isn't much difference.
Having done this - on and off for a year now I am very aware of the power of the body clock. It is interesting - but you can be awake for 26 hours. And totally exhausted. Yet - often - a couple of hours later your body kicks on into 'a new day' and you are wide awake.
The whole thing of skipping sleep is quite interesting. I have heard some artists use it as a 'high' to help them be creative. Apparently My Bloody Valentine used sleep deprivation as a tool when recording there classic 'Loveless' album.
Still - in my case - I am hardly skipping sleep. Since by waking up at 2pm - and then going to bed at 7pm (the following night) - it is more like just staying awake for along time. But - your body clock does perceive it as skipping a night's sleep.
Sleep deprivation is also an effective (albeit temporary) cure for depression.

Anyway - after thinking alot (and experimenting alot) with sleep patterns a year ago. I was pleased to find out that R. Buckminster Fuller did the same thing when he was alive as well. Since he was one of the most interesting geniuses of the twentieth century.
