Well Honey it really sounds like you've got your head screwed on, sounds like a very sensible approach, and you're right you do need to be in the right frame of mind for this diet to work. Remember you can always come on here for support in the CD threads i spend most of my evenings in there recently, sad i know lol.
Wow have u got any pics of this other dress you want? Sounds like a lovely present for losing all your weight in my opinion hehe. I'm at a wedding tonight and got nothing to wear :'( well i probably have but haven't looked in my wardrobe yet it really sounds like you are motivated to lose the weight and we'll all be here when you need that support (((hugs)))
