Mike, in holosync, one zonks out due to the brain being overwhelmed by that particular stimulus. In time the brain reorganizes to a higher level & one does not zonk out any more.
If i were you, i'd continue to listen to it till you stay alert thru the entire tape. This way you'll know your brain has fully reorganized to a higher level of performing.
Thanks for posting b/c i am also going to revisit witness & release. Thanks also, Pete
