Just started the Nutrologie 6 week bikini diet..

Hi, I'm on week 1 day 4 of the Nutrologie Bikini diet and all is goo so far. Shakes taste good but after putting them in here I'm surprised at how much sugar is in them! I ached like mad after the first day of exercise and had to take it easier the following day. Ok today though so will be going to gym.
Anyone else tried this diet and if so, how did you find it?
Thanks
