so i was thinking could i cut out the whole WBTB thats part of rythmn napping an just wake up say 9am an do the intervals of 4min, 8min, 12min. etc.? or would this make it not work? personally i think it would be more useful without the WBTB for me. being the fact that if i stay up longer than say 10min i cant fall back asleep no matter how tired i am. so whats your guy's opinion? should i keep the WBTB part when attempting rhythm napping or not?
