Just a suggestion. Check out the John Morgan seminars for weight loss (and stopping smoking) hypnosis. Worked for me at a fraction of the price ($65.00), and attendance at one gives you free admission from then on.
He also sells the DVD's and other material to help.
Normally the seminar circuit tour is mostly held during the very early spring, after New Years.
If you can do it this way, more power to you. Last time I lost 135 pounds, I did it using diet changes, hypnotism, self-hypnotism, and everything else I could think of using. It took 18 years to regain the weight. You can still defeat weight loss surgery, but the chances of being able to do so are rather small.
