I am going through the same process right now. I was banded 8/21/08 and I find myself sooooo hungry through out the day that I feel I am eating constantly. I talked to the nurse about this and she reassured me that is normal. She said #1 they want you to eat healthy right now and not to be concerned about losing weight. The process until the 1st fill is getting your body used to the band, healing from the surgery and getting yourself used to eating properly (i.e. chewing throughly, not drinking with meals, to stop eating when your full, etc). For my hunger problems she just suggested I eat more foods that I have to chew and will stick with me longer. My body isn't sustaining the foods I am eating therefore making me hungry all the time.
Don't be discouraged though. I know you are like all of us...so ready to get this weight off and get on with our new life. But until we get to our 1st fill we just need to concentrate on how to eat and make sure we are healing ourselves.
Hope this helps!
