2.3 When those methods worked, how have I inevitably lost control and overeaten again, putting back on the weight I worked so hard to lose? Explain.

I think that once I have lost the weight (even now) that I can dabble in the 'forbidden fruit'. Its okay to have that dessert, that extra serving of pasta, that pint of ice cream because I know that I can lose it later. And besides what is one extra serving going to do to me and my weight - after all its only one little bit more.
Boy can I justify it .... its easy to say it won't make that much difference and I have the will power to control my eating tomorrow. So today its eat drink and eat some more.
I find sometimes when I have broken my abstinence, that I will say to my self "Well since you have already cheated you can do whatever you want today." As if there's someone keeping a score card and once you have blown it you might as well get everything that you have wanted but couldn't have. The irony is until I realize that I have to replace the 'want' with the 'need' and only look for the things I need. I am usually about the want not the need.
