brandnewbie, I totally hear you. Personally, I am just staring my journey here (likely will have surgery on August 19, but still hasn't been submitted to the insurance yet). I feel that if you're going to go through such a life-changing procedure, you mine as well get started following the rules as soon as possible to better prepare yourself for a new lifestyle!
That being said, I think these boards are a great place for people to come to relieve their burden if they make a mistake, or fall off the wagon, etc. because people here truly understand how difficult it can be to change food habits that you've developed your whole life. I don't want to think about the fact that I will likely have some small setbacks, but the reality is that it could very well happen. Really, I thank the people who have the courage to admit when they've messed up, because it 1) makes me feel like we're all human and in it together and 2) that I can understand what setbacks may be coming to further prepare myself for success.
