Does anyone out there know of a good system for re-setting wacky sleep patterns?

I am addicted to television and set my machine to record many things but also watch it live or any of the hundreds of DVDs I have in my collection. I have every Star Trek episode and movie ever created. Plus whole box sets of Gilmore Girls; Firefly; Farscape (brilliant Australian sci fi); Buffy The Vampire Slayer; Angel; 30 Rock; Stargate SG1 & Stargate Atlantis on top of about 100 movies I have bought from the sale bins

Currently I am finally getting to bed around 4am but even then need to read for about an hour before I feel I can sleep. I then wake around 7am and then need to sleep again from about 9am to around 2pm in the afternoon

I am not on any drug regimen and only take supplements (like multivitamins and fish oil) each morning

I realise my problem is probably more about television addiction but the issue for me is wasting my days sleeping!!!

ANYONE GOT ANY PRACTICAL ADVICE ABOUT ANY OF THIS?
