I don't think that there would be any reason to do both. Choose one or the other. I went with plication because there was nowhere here in Ontario where I could get fills if I had lap-band surgery in Mexico. Having said that, I am two months out and down 17 pounds. I lost 12 pounds in a about 3 weeks and have only lost 5 pounds since. They say that I would have such restriction that you could only consume half a cup of food at a sitting. I have not found that to be true for me. I certainly do eat less but you have to be very committed to making the right choices and not eating mindlessly. I've been stressed with work, moving, and an up-coming law-suit so it has been difficult to stay focused. It is not a magic pill and the OCC doesn't claim it is. From what I've heard, when a lap-band is properly filled, a person can have an easier time preventing themselves from over-eating than with plication. Think about it and make your choice based on your lifestyle and research. I think this can be a great life-changing experience-if you are willing to commit. I am saying this more to myself than to you. I look forward to taking my own advice when my life is a little more settled.
Best of luck
