Glad to hear you had a good visit with the surgeon. Funny...steak and bread were the two things my surgeon warned me against as well. Any pains you had prior to the surgery will, as you suspect, take some time to resolve. It took you more than 15 days to get them, and it'll take more than that to get rid of them.
As far as the MAD GURGLING STOMACH...I can only share my own experience. I'm two years out, and from time to time my stomach still gets "gurgly". It's rare, and seems to accompany having eaten something that irritated my wrap. It is generally accompanied by "dumping", when things pretty much go right through me. Thankfully this only happens once in a great while, so it doesn't really bother me. I know what you mean...I was at a meeting at school in the early days, and people were offering me food, thinking it was growling due to hunger! It is loudly embarrassing. Some people never have it after they heal, but I am not one of those. We just laugh at it. Hopefully yours will resolve with healing, and you'll never hear from it again.
Everyone wants to stop their PPI's after surgery. However, during the healing period, when swelling can allow a bit of acid through, it's a good idea to follow your surgeon's advice and stay on them for a bit. As you know, however, some people have to continue with some PPIs after surgery. It's very individual. Still, most are very happy with their surgery, even if they have to take some meds, since their symptoms have subsided.
Best wishes for continued healing!
