Failed attempts to re-set my body clock (part 1)

Over the past few days I have been doing my best (a) to try to go to bed at a normal time (even though I am awake) and (b) trying not to sleep in the mornings. The result is that I feel awful!!!
I have been succeeding in not sleeping in the day and utterly failing to sleep at night. You would think that the sleep deprivation would enable the catch-up mechanism to fall into place so that night sleep can take place. In my case at least, it does not.

I found an interesting link about sleep and the circadian rhythm

http://www.abcbodybuilding.com/magazine03/analysisofsleep.htm

It includes some research by a Dr. Wozniak (whose work I will try and follow up on) and a recommendation for people with DSPS which is not unlike the others I have read. Maybe I should re-attempt using my light box to shift my sleep pattern bit by bit instead. But I get the impression that I need to freewheel first and get some proper sleep. Free-wheeling (sleeping as and when I needed it) was what I was doing after my rhythm broke down this year. Although it did not fit well with my university studies and I was not fully functional, at least I did not feel like I feel now... totally shattered!!
