I have a question, Do you still have your Gaulbladder? or is yours having problems. When I had Gaulbladder problems I couldn't eat alot of fat, because my bile was all messed up. After I lost my gaulbladder I still couldn't eat alot of fat. When I started Atkins, at first I had a similiar reaction as you. I think its because I was used to low fat. I increased my fat slowly and now after three months I'm used to it. I think it takes a while to adjust to any diet changes. My two cents
