VSG to RNY

I had VSG almost a year ago and have been very successful regarding weight loss and hit goal at 9 months. I'm getting ready to revise to RNY due to refractory GERD. I'm constantly spitting acid out and have significant pain all the time from it. I've gone for multiple opinions and the opinions are all the same. Can anyone that's undergone this type of revision give me any feedback on recovery and pain levels? Also, how different is your diet vs. with VSG? I eat protein first then try to fit in a couple of veggies if I have room. I appreciate any feedback!
