I think it's a good idea, away from food while going through the most difficult part of the diet would be good. I also think that if you could do little workshops, such as someone who was able to talk about CBT and how it can help you succeed, or how about one about dressing to suit your shape, kind of thing?! If you could also get someone like a beauty therapist in, who could give massages or facials, etc, to take the mind off the hunger, I think it would be brill! Nothing better than a pamper weekend. I'd pay a bit more if you were providing that sort of thing, rather than something I could do at home.
