I noticed that freedieting.com link had links to Medifast, a plan where they sell you a packaged plan...like 4 weeks of food, etc.

Has anyone here used this? I am considering it for a very short term. I am a little out of control right now, and also seriously crunched for time, so I thought maybe just eating what I was sent, totally pre-packaged so as not to have to make portion choices, make time to shop/cook, etc, might help sort of snap me back to some healthier habits and help me get back on track.
