Have you found anything out? Have you been scoped? I had problems with vomiting and nausea - went to the er and they did a cat scan and x-rays, everything seemed fine they said, but I was the first patient they had ever seen with a sleeve - I still couldn't keep anything down and knew something was wrong, so I found a local VSG surgeon (I was sleeved in MX too), who would see me with my complications. He did an endoscopy and I found out I had a stricture (not found on ct-scan, had to be found with the endoscopy).
I was in the hospital for 8 days, not fun,but I am so much better. The doctor put a stent in, which was uncomfortable, your stomach's function is to push things through, so it was very awkward and uncomfortable. I tolerated it for 5 days and it was removed. That was a week ago. I feel so much better.
I just want you to be aware that there are other problems besides leaks, that require additional testing. If you are still having problems, see someone local.
