I was banded in November.  Including Pre-op and Post-op I have lost 75 lbs., but I have gained control of my life again.  I still battle head-hunger on a daily basis.  Up until my 4th fill, I really second guessed my decision to be banded.  I could tell it helped some, but not as much as it should have.  Now, after my 4th fill and I hit my "sweet spot", I love the band.  It was like, I finally got how wonderful it is.  I am starting to look at food differently.  It is beginning to lose some of its attraction.  Don't lose hope, stick with it.  If you think you need a fill, get one.   
My husband got his band April, 2009.  He is kicking my butt on the amount of pounds lost.  He is coming up on 100 lbs. lost including pre-op & post op. 
It has made it easier on me having him join me in the journey. 
If my band ever slips, I will get another one just as soon as Dr. Ortiz will allow it. 
Good luck, 
Kimberly
