I participated in a QHHT session because there were and still are,  many emotional issues in my life that I can't figure out, so I thought this could possibly help me.  My concern being under total hypnosis was if I was going to remember anything or forget everything.  I understand that hypnosis isn't necessarily for entertainment, like barking like a dog when you hear a whistle.  It calms you and helps you figure out your thoughts.  The best way to prepare for a session, I believe, is to go with an open mind and not with any preconceived notions.  It was very relaxing but at the same time emotionally draining.  Tim was very nice, calming, non-judgmental so I felt comfortable, and that made the session easier.  All I can say is go in with an open mind. After listening to the session recording I was a little weirded out because I essentially heard myself almost talking in my sleep.  It was basically a confirmation of things I already knew, but needed to hear out loud. It helped me embrace vulnerability, which after hearing some of the recording helped me understand that that's ok.  I believe if I follow some of the things I said while under, and meditate, it'll be a less stressful life.  I would say absolutely try it, if you are struggling with emotional issues or anything you cannot figure out, this may be the way to go.
