I had the band and it did not work well for me. I had horrible shoulder and neck pain for years due to the tubing hitting a nerve. As soon as it came out the pain was gone, so now I am having the bypass I am a little nervous hoping the pain doesn't come back:) good luck
I have only used the water method also, and has worked grat for me plus i really dont think that any extra radiation is good for you unless you really need it.
