It seems that you aren't getting a lot of responses but maybe thats because Atkins doesn't advocate the type of fast you are talking about so there aren't many "experts" on it here. Aren't you afraid it may mess up your metabolism if you do it for that long? I really wish I could be of more help. A long time ago I did a weekend fast where I just drink water with lemon juice in it (it was a fad at the time.) I lost 4 lbs. which I promptly gained back when I had regular food. As far as detoxing, what are you trying to detox from? By the way...your pictures in your profile show me a beautiful woman that looks great. Your weight and height are appropiate already so maybe you don't need to lose any more. Just my thoughts. That and $1.00 will get you a diet Coke most anywhere in town. I wish you luck and maybe someone will come along that can be of more help.
