dont wait - I am 11 months almost post surgery and still do not have restriction from my band, it may limit some food items I can eat, bu amounts etc it doesn't, it also hasn't taken away my hunger.
What flutterby has said is right, take control don't wait for the band, this is about your choices of what you eat and it isn't just about restriction because you most certainly can continue to eat the wrong foods or too much. And it can take a long time to find it!
