I've had the band for 10 months and have had no physical problems from it but it has not worked either. I can't eat anything. The recommended 4 oz portion is too much to eat, yet, no weight loss. I've gained 3 to 4 pounds. When I posted it, I got one positive response as to what the reason may be and one response with a definite blaming tone toward me. I followed instructions to the T. Am anal about counting every calorie, exercise more than I ever have in my life, but get nowhere. I can't help but believe there are others out there that have had this same problem occur. I have to admit I was concerned about posting the problem because I knew many responses to others with problems were all negative and played the blame game on the person who posted.
