Wow, I just found out that I need to have mine removed as well. I was sleeved in July 2012, two years ago! I remember reading that we are high risk for the this type of issue, but I can't find the info.
Well, congratulations! Um, well, um... I'm 4 years out today. I guess I've been "lucky" so far - still have my GB and as far as I know, no issues. Good luck and good health to you! And to Indy9771 also!!!
