Query: This is a HAPPY diet!

I have tried various diets before and have been miserable on each and every one of them, until I tried the Atkins diet. This is so wonderful. I do NOT feel deprived! I am NOT hungry! :) I eat according to the diet and am very satisfied. I don't get hungry 15 minutes later either. This is just so much fun!!! And YES, I am losing weight!! I feel good and am lookin' pretty good too! I have also noticed that other health problems I'd been struggling with have just kind of faded away. (chronic headaches, achey muscles, fatigue, and other things) I haven't had my cholesteral rechecked yet, but I look forward to going to the doctor to have that done. I'm buying this set for a friend.
