Yes, you are definitely working yourself up lol If you know it's the right thing for you, don't psych yourself out.
I am one of the very unlucky ones that has to have a revision. I never had gerd or reflux before my surgery, so I chose the sleeve. I have LOVED my sleeve. Unfortunately, it caused horrible gerd that also caused gastritis and esophagitis, so I was put on 80mg of Nexium. I've been on it for 7 months now, and it caused polyps all through my stomach. I've had 2 surgeries to remove them, and now nodules all through my duodenum, which also have to be removed. Once they are, I'll be cleared to have my revision to bypass. I'm told that should take care of the gerd, which will allow me to get off the Nexium, which will stop the formation of polyps and nodules.
I still don't regret my sleeve. I've lost over 110 pounds, gotten off all 3 of my diabetes meds, gotten off my blood pressure med, my mobility is way way better, I work out 5 days per week, all my labs have come back normal repeatedly, I can honestly say it's still the best thing I've ever done, even with the complications.
