I have suffered with reflux for years. I have had no problems since I had the band surgery. I expect that with more weight loss, it will be gone entirely. I asked my doctor about it because I had heard the same thing, he said he has never known of any of his patients having any problems.
As far as number 2. I also have tried everything, from the time I was 8 years old. If you read the post by Big Paul about the truth about the band, your question may be answered. The band is a tool. You still have to work with it and change old habits for it to do it's job best. All it can do is restrict the amount of food you eat. You still have to make better choices and drink alot of Water and try to exercize as much as you can.
Good luck to you with the fertility journey/or adoption as well as with your choice about the band.
