How to get rid of sleep-o-holism?

[Vektor]

I went to sleep last night around 1 o'clock, had the alarm ringing at 9, woke up to it feeling awake and energetic, but I continued the worst of my habits again, shutting the alarm and starting to lay again in the bed for "just a few minutes as being in bed in the morning feels so unbelieveably nice and comfortable" and falling back to sleep until rising up at maybe 13:30(1:30pm)!

And this happens very often, it is rather a rule than an exception on the "free" days when I don't have to go to work early in the morning. Sleeping like 12-13 hours a day, what an unbelieveble amount of time it consumes, and what a frustration it creates. But still, the temptation of going back to bed after the alarm has gone off is strong almost every morning. The dreams in the late morning hours are often very vivid and "nice", making me want to stay in the dream world.

The oversleeping seems to happen often if I write down or otherwise just decide many (often even interesting) things that I'm "going" to do the next day. My subconscious or something sabotages my day by preventing me from achieving those minor everyday goals because I'm sleeping. Maybe my subconscious is just afraid of the possible discomfort of doing things? Although I can consciously perceive that being unproductive and wasting time creates a lot deeper discomfort!

Last summer I tried practicing getting out of bed many times in sequence beforehand like Steve Pavlina advised in one of his blog entries, and that helped me getting out of the bed better, but I think that's not the problem, the problem is after I've gotten out of bed and shutted the alarm. How to get the mind working, motivated and to see the whole picture of my life, instead of seeing going back to sleep as the most "optimal" solution? Any ideas on getting motivated immediately after rising up? And any other sleep-o-holists online?
