Are there any DSers in this group? Why no posts since May?

Hi, Saw a link to this group and thought I may find some valuable information and fellow-DSers I can bounce things off of regarding using Atkins as a base for losing weight with the DS.  I'm coming up on 2 years since surgery and have lost 141 pounds; 6 pounds in the last week.  I'm wondering if there is a minimum number of carbs and a maximum number of carbs (in grams) for losing weight on the DS.  In my research, it appears 50 grams total per day is right for losing weight.  What would be the allowable deviation to shoot for?  No more the 51?  60? in a day?  what about in the other direction?  No less that 49?  20?  Any help is appreciated!  Anyone out there?
