Glen remember the band is a tool, nothing more nothing less, you can sabatogue it too if you try. However, the band can keep you honest as you learn to eat and make choices that are the best. As for being nervous, try not to be. Dr. Yau is one of the best. I flew from BC to toronto and back within two days. Just take loose fitting clothing, gas X and you should be fine. Without the band, you know you have failed the in past but with the band you more than likely will not. I have had the band 4 years and although I have had my ups and down (recently gained) my overall loss for the year was 7 lbs. I have never in my life lost weight 3 years in a row. I am a slow looser because my choices are not so good at times, but the band can not be faulted. If you post on your clinics website, you find find they have terrific web cam chats and support. Good luck
