I've been tested by my doctor and found to be lactose intolerant. I had no idea. But my big mistake since on this woe is that I thought that cream, butter, yogurt and hard cheese had no lactose and now I am also experiencing a gain. I have been eating creme fraiche like it's going out of style.

People on this board have been helping me and I will now start the next week on a total non-dairy regime to see if that will make the difference. I am determined to be thin again!

Sounds like you definitely have a problem with dairy too. Good luck in your trials. It takes a little time and patience to find what will work best with your body.
