Lapband to Gastric Bypass - share your experience!

I had my Lapband placed in October 2007. got my gallbladder removed and a hernia repaired at the same time. It slipped in 2013 so had surgery to put it back into place. My heartburn has become unbearable so my doctor is recommending to remove my band and get the gastric bypass. I was scared at first, shaming myself for "failing", telling myself who am I to think I am worthy enough for the bypass when I couldn't succeed at the Lapband, blah, blah, blah mental games. But then I recognized I am blessed to be able get this opportunity - that I am not getting any younger so better to help myself be in my best shape now than later. So pending some co-morbidity approvals, I should be well on my way to converting. I am scared. I am excited. I am hopeful.

My question is for those who converted from Lapband to Gastric Bypass - what are things you wish you knew about or understood prior to converting? Or things you learned about since converting that would be helpful for someone going through the same process?
