The simple answer is
You can do whatever you believe you can do. Begin by believing that you can do this 1 meal at a time. Stop looking a the BIG picture and start taking small steps toward a bigger goal. Believe that you will drink your first meal on the first day and after breakfast busy yourself with other things, at lunch drink your 2nd meal and so on and so forth. This is not easy but one meal at atime you will begin to feel accomplished... Believe in yourself that you can and you will change how you think, feel and eat food. We all have those same fears, doubts and emotions and that's why we have been banded or are thinking of being banded. We all have a poor relationship with food. Consider that you are working on your relationship with food.
