Don't 'start over.' It's like admitting failure. Instead, GO ON. I doubt that losing weight is the only part of your life where there have been ups/downs, good/bad moments. The success/failure mentality is rarely helpful in living, and it's definitely not helpful in any process like losing weight or getting healthy.
As a pp suggested, more information would be helpful for anyone wanting to offer suggestions. In general, though, inflexibility is a huge reason people have troubles. Cutting out ALL of a favorite food, insisting on maintaining an unrealistic set of expectations (exercise, calorie intake, whatever), making too many big changes at once--these are reasons we rebel from the inside and suddenly can find ourselves acting out against our better judgments.
Some people find a 6/7 regime works, or do what they call 'cheat' days (I don't care for the term or the idea, but it seems to work for a lot of folks to keep the discipline at a reasonable level).
Others find weighing/measuring before they taste anything to be a manageable strategy for long term success. (I have to do some of that; my eyes 'shrink' portions over time, so a cup of cereal can become quite amazingly large if I don't keep a scale/cup around).
Many find the community to be very helpful--either the message boards as you do, or building a more consistent relationship with others who share interests in a team.
Ultimately, the commitment to go on comes from within, and that needs our wholehearted interior cooperation.
Good success to you.
