KV,

You've had a lot of good advise here... so, mine will just be the "mommy" advise. I would call the Atkins centers and talk with one of staff about your gallbladder surgery and staying LC. There's probably no problem but since we are not medical professionals and this is a medical issue... you should discuss this with a professional. The Atkins program helps so many people with all kinds of medical dilema's ... and yours will probably be the same. But i would just be safe and make sure!
