I pulled out a prototype self hypnosis cd I made in 2007 giving the mechanics of releasing endorphins into the bloodstream. A few minutes into the suggestions, the cd skipped. I smiled. It skipped again. And again. I began giggling.  So it worked! Even though I didn’t get to hear the whole cd, endorphins got released.   I’m always making hypno cds for myself  for whenever I want to reprogram a thought quickly.  This one, though, is purely for pleasure.
