I am also in my first week. Started on Friday. I have 30 lbs to lose and I have always been a slow loser, but I already feel slimmer. My center sell the packets individually so I have had a lot of variety and I have really enjoyed everything so far, especially the soups, pina colada drink and pineapple-banana. The SW cheese curls are amazingly good and spicy. I have not been hungry at all but I had no energy on Saturday/Sunday. Today (day 4) I feel great. Good luck to all :)
