I also had a hernia and GERD and ended up with a revision to RNY about 2.5 months ago. No regrets at all, my GERD is completely resolved. Even though I struggle with food getting stuck (my sleeve stretched and my pouch is smaller than normal) I have zero regrets.
Folks can have uneven weight loss with any surgery, I suspect it's all a matter of luck. I'm down 38lb and have none of that so far, I'm saggy in a completely even fashion!
