I have one more swl appointment and then i start my preop appointment and diet.. Im not trying to tell anyone what to do or scare anyone but my doctor had a patient who didnt follow the rules in the end when your not suppose to have food and when he started surgery, already had her cut open she was full of food. He was so mad because she could have died. Luckly she didnt.. they just pumped the food out and went on with the surgery.
