Don't get frustrated yet, give it time to work, when your band tells you you are full stop, but you can't eat what you want and think your going to lose, I'm not trying to be harsh, just trying to help, the My Fitness Pal does work, just keep logging your foods, and the amount.
Yes I have tried this 5 day pouch test, and it does work, I loat 10 lbs in a week, because I did have a small peice of my sons birthday cake one day, so I tryed it, I can say it works.
