Yes, it's an all-around-the-clock-thing. Right now, the first night is over and I expect my first difficulties during today (some irritation, some problems with concentration and motivation) but from experience I know that this is just a phase to overcome.
Oh, I use Deep Relaxation for two reasons: If I'm for some reason not tired enough for a power nap I will at least relax and re-energize and if I fall asleep, I wake up at the end of the tape with pratically no "hang over".
Hope this helps,
Jens
