I am sorry you are feeling down. You have to remember that the band is a lifestyle change and the weight should take 1-2 years to come off. It took me awhile to come to terms with that, but I finally have. You have only just begun your journey with the band, so don't give up yet. Once you get a good fill you will be very restricted as to what you can eat.
I had to wait awhile for my fills too, so I know what you are going through. Hang in there!
