I hear you! The first night of liquids, when I was driving home, I swear every sign on the road was for one restaurant/fast food joint/pizza place or another. And I found myself thinking, "How would they ever know?" BUT...over the summer during the pre-testing/jumping through insurance hoops stage, I went through a very big "@$% it all, I'm having surgery soon so I'm gonna eat what I want" phase...and gained 9-10 lbs. When I went back in for a visit with my surgeon, he wouldn't schedule surgery until I started losing again. I definitely don't want to get to the hospital the day of and have him cancel because I gained again!
As for the weight tracker--I just figured it out, we'll see if works when I post this. On the web-based boards (not the iPad app) at the very top of the page on the right, there's a blue header that has an envelope, your avatar and your profile name. If you click on the down arrow next to your name, a pull-down menu with a bunch of different options appears. Go to "My Tickers" and follow the directions. (BTW, I didn't know either until I saw your question and started investigating )
