I was banded on Oct 1 and am just starting to get the hunger pains you are describing- I am also drinking Protein shakes for Breakfast and lunch with light Snacks like yogurt as a filler. But, I have stalled in my weight loss, lost about 45 pounds since starting the pre-op diet- I asked my surgeon last time I was in (for my first post op appt) and he explained that I may not see any pounds come off right away, but more inches. I didn't want to hear that- but it has been true- I have lost 4 pant sizes since starting the pre-op diet. I am hoping that my first fill gives me more restriction.
Don't eat anything that you aren't supposed to- you can really hurt yourself- so even if you think you have no restriction, you do and you won't find out until its too late....
