Not sure if this is what you are looking for, but I say give WW another chance. However, your mind TRULY has to be in the right place or you won't succeed. You have to be willing to WORK at the plan -- nothing comes easy.
Here is my story --
I too have been "over weight" majority of my life -- since about 3rd grade. I have yo-yo gained/lost several times over the years, but reached my highest weight (270 lbs -- height 5 ft 11 in) after being pregnant with my son. I have never truely considred surgery because 1) I know I want another child and 2) because I know that if I don't change the root of the problem I'd gain it all back anyway.
Last October, after seeing a picture of myself with my family, I had finally had enough. I started following an atkins plan and lost 50 lbs by late Feb. From there I have gained/lost the same 10 lbs over and over.
2 weeks ago I switched geers and have joined Weight Watchers Online. During the first week I lost 8 lbs (mostly water weight obviously). By switching things up I have "refound" my motivation. Current weight is 226 lbs (44 lbs down from the 270 of last Oct.) My goal is 200 lbs.
I believe you can do it -- and if you want an "online buddy" let me know. Best of luck.
