Absolutely you are going to be nervous. But from my view, I kept thinking I will never eat....... That again . Well I have no desire to want that either. I had surgery 12/11 and lost 41 lbs and feel great . This is the best thing I did for me ever. I am going to be 60 end of February and I just say I am going to be a sexy 60 yo . It is a slow slow start and when the pounds start melting away you will be glad you did. I was also a big carb eater and since 1 week before surgery I have not touched not even a little drop of carb and not lost without it .
