Today was my first class. My husband, my biggest support for 45 years went with me. The presentation covered the types of surgery, the nutritional needs and the behavior health issues. I felt good about all the info until the surgeon that said I may never eat ice cream again! Kaiser Permanente is very good. It will take 6 to 8 months of pre suegery work before I finally get the sleeve. I have my first nutrition appointment next Tuesday and have my mental workup tomorrow morning. I was a little freaked out about the # of calories you will live on.....I still wonder where you get energy from ? Things to ask The nutritionist. Later friends
