First of all Merry Christmas.
I never had GERD or stomach issues before the sleeve. I have had 2 endoscopies and I have non-healing ulcerated stricture of the esophagus which was caused from the GERD thus the 2 pantoprazole a day.
I now weigh 163, I forgot how to change my weight and ticker, and I did it by Intermittent Fasting - I eat only with in 8 hrs a day. I'm amazed how well it works and I do low carb. My goal is 142 lbs so 21 to go and I'm doing it by intermittent fasting. Lots of FB groups for it and info out there.
Research the good and the bad of surgery. I would also suggest before surgery trying IF and low carb. I don't know how much you have to loose, your age or health but with surgery there is no going back. Truthfully if I had to do it over again I wouldn't of had surgery. In truth I wanted an easy and fast fix. Surgery is not it. I have had to take stool softeners since surgery due to constipation. One good thing it did was normalize my BP which was only a little high.
I hope I've helped you a little with your choice and please remember there is no going back after surgery so research all you can and the Dr doing the surgery plays a big part.
