Karmin, are you understanding that the band isn't supposed to restrict you until AFTER your first fill, which you cannot have until 6 weeks after surgery? So, if you are hungry now, thats perfectly normal. The restriction and weight loss doesn't happen until after the fill itself. You must heal from the surgery before they can give you a fill. Just drink as much fluid as you need too to be full and it will pass. Once you get your first official fill, you will be doing much better.
And incidently, there was a day or two during my 3 week post op that I thought I was going to die if I didn't eat. But, I didn't eat, didn't die and the feeling passed and I was fine again. So, just hang in there!! It will be ok in the long run.
