I'm recently banded as well and my 1st fill was also 4cc to make mine a total of 5cc, my MD informed me that I might not see a big difference in my feelings of hunger, she told me not to feel bad but just to try and stay on track and eat healthy meals. The reason I say this is cause I told her that I didn't feel much of a difference and she told me that I might not. While I'm not hunger 2 hours after I eat , I feel that I'm able to get more than than 1 cup. I say just stick with it and try to drink you Water, that's what I'm doing and good luck!
