Mgordon,Congratulations on your success. My daughter has been on the ATkins Diet for 1 1/2 years now and has gotten her quality of life back. Her IBS led to FM/Myofascial Pain Syndrome, MVP, Endometrosis, the list goes on. Some of these things she is now stuck with but her FM/Myofascial Pain Syndrome plus IBS are virtually gone, all because of a change in diet. Pretty amazing when you think that there wasn't any doctor to advise us on it and if it hadn't been for the fact I had read the Atkins' Diet book and followed his advice, my daughter would still be laying on her bed in my house in very bad shape.The Dude,My daughter had severe, I mean really severe constiptation, the kind that makes you curl up on the bathroom floor in pain and put you in the hospital, several times in fact.The Atkins' Diet saved her life, she does however take Magnesium, she regulates how much of that she takes by her stools. If she has diarrhea, she may even stop it for a day, then she'll start again with 400 mg. a day, then she may up it to 1000 mg. always depending on bowel tolerance.She feels she is now in control of her IBS and has gone back to a full normal life.RedfernAs far as losing weight, my daughter weighs around 100-106 during a year so she can't afford to lose weight. She believed that getting rid of the IBS overrode her worries about losing more weight. Since she now has her IBS under control, she doesn't follow the diet to the letter anymore so she really isn't losing any more weight. She lost 6 lbs. the first week but has since regained it. Goodluck to you all,Casey
