a lifetime ago I tried it...along with ear staples they said would suppress appetite.
(Some doctor running a practice in an expensive office in mid-town NYC)
never went back.
My reaction is ... it's like looking for a 'magic pill' that will convince someone to do what they already know they should be doing. If hypnosis is a suggestion to the subconscious mind...aren't we already bombarded with all kinds of suggestions that we need to eat healthy and exercise to lose weight.
Bottom line...a person needs to decide that they want a better life and commit to making changes ...otherwise, results will probably be short term at best.
Are you getting sleepy yet
