Hi Elizabeth,
I am in a similar situation with food issues. I know what the right techniques are and I have all the tools but for some reason I find it difficult to take the plunge and really commit myself in to the long term lifestyle change I must make in order to control my weight. I have actually purged a couple of times, but true to my lazy form I find it too taxing so I don't do it anymore. I would love to have a buddy so if you are interested we could definitely be each other's motivators.
