I have lost 28 pounds since my banding on sept 21.  everyone goes a their own pace. -10 is better than +10   just hang in there!  I know how disapointed you are.  
What I do since i have no restriction yet is make sure i dont over eat . I estimate what I would be able to eat with a adequate fill and keep it there.. yes i starve but I have always been able to starve off the weight, I was banded to KEEP it off
