After a few months you get totally comfortable with it.

Imagine what you could do with 22 hours in your day, eh?

Pity it's so difficult to adjust to.
When do you sleep just at night or spread through out the day? and don't REM stages take more than 23 minutes to occur. How do dream let alone become lucid.

as for the CAT method it sounds like a very good idea except that i already wake up at 5:10 every morning and waking up at 3:40 doesn't sound fun. but i'll give it a try.
