I am going to try the WBTB technique today, but I'm having a problem to decide which one is better.

Which technique should I use:

1. Wake up after 4-6 hours of sleep, be awake for 30-60 minutes, and sleep again.

or this one:


2. Wake up 1 hour before your normal waking hour, be awake for 1 hour, and sleep again.




Which technique is better?
