Hi wannabeslim,
Hun you have to do what feels right for you, I have tried 790 and 1000 and personally i couldn't do either, i am sort of an all or nothing if you see what i mean. There are plenty of people that do the other cd plans and they work fantastically so if you feel that you could do it then go for it. But i have to say of you can just get over the next couple of days then you know you will feel so much better and the hunger etc will decrease and generally you will start to feel lighter and more energetic, However if this is going to work you have to do what you want to do otherwise you will start to stray and you are not allowed to do that hun we are in the july challenge together, just think how fab you will feel when you havelost the 21lbs you set yourself.
Good luck hun with whatever you choose to do, keep me posted.
Love BusyXX
P.S I am on MSN if you fancy a chat.
