As it sounds from people who have replied to you post, many of us have went to WW, many more than once and many who have been successful but eventually put the weight back on.
I after being frustrated with my weight, found overeaters anonymous. It is a 12-step group that deals with weight. (pm is anyone is interested in hearing more)
Part of that that I currently do and will help you with WW has to do with recording your food. When I did WW I would start out writing down my meals, adding up points, etc. I never made it too long before I would have eaten all my points far before the day was done. I suggest writing down your food the day before or morning of the current day. Make sure you go by that. You know exactly what food you have in the house and what you are eating each meal - no guesswork.
Good luck!
