I think Chris hit the nail on the head with her comment about being absolutely truthful with our doctors. I know for me personally, I was so afraid to share some of my eating behaviors because I was ashamed of them. The very first time I ever talked publicly about an eating behavior of mine was when I was at WW about 13 years ago. I talked about sitting in front of the TV with a cheesecake and a fork and eating the entire thing in one sitting. A woman disgustedly replied, "Oh, I don't think I'd EVER eat THAT much food!" At the time, I was hurt. I felt like a total freak! I didn't share anything like that again until just a few years ago, on these boards, in the relative anonymity and safety of the Internet.
It's that sort of thing we have to get over, though. Trust me - your doctor's heard a lot worse things than how you can eat an entire meal at a friend's house then go through the drive-thru for a double cheeseburger and fries, or how your entire self-worth is wrapped up in Monday's number on the scale. Being honest is so important. If you get a dickhead doctor who gives you crappy advice (like Jessica's doctor, and I'm frankly surprised she didn't slap the s**t out of him!

), find another doctor. Get a second opinion.
Here's a thought: Just like there are doctors who graduated at the top of their class, there are doctors who graduated at the bottom of their class.
