Durka Durka,
I had the same doubts, I put months of saving money into this program- but beleive me it is worth it. It is impossible to not lose, unless you are doing something wrong- and if you are it shows up in blood tests and you will be able to fix it. Some lose quicker than others, so it may come off quick or slow, but it will absolutely come off. Seriously, we are not commissioned people who bombard forums trying to sell the program, everyone of us is real, big, sick of it all and tried nearly everything!
Starshine, you will not regret giving this one a go, I have never stuck to anything my whole life (coming from a girl who has two unfinished degrees and a very long work experience list and moved house more times than I can count on my fingers and toes) but for some reason and God only knows, I have stuck to this. The beautiful thing about this program is that it is so strict that you surprise yourself everyday- everyday is a huge success. And you will be a skinny mini in no time
