Most hypnotist will charge up to $150 or more per 1 to 2 hour session. AND they usually tell you that, regardless of what you need help with, you will probably need to come to 6 session. Please see the chart below.
I charge $125 per session and my sessions last 15 minutes instead of an hour or two and will achieve faster results and here's why. Remember that most hypnotherapists will spend half that hour getting you to relax before the therapy. I do it in 2 minutes. And most hypnotherapists will install negative reinforcements like telling you that if you are around a cigarette that you will develop a bad taste in your mouth like throwing up. Since none of us want that taste, we will reject the idea altogether and keep the habit.
