I have not experience, but did a little research.

Sneezing at the end of a meal could be an allergic reaction to something you ate, it has also been linked to the stomach becoming full and, thus distended. Hiccup's after eating often is related to eating a large meal, drinking alcoholic or carbonated beverages.

There is actually a word to descripe the sneezing after meal, "snatiation" , a blending of the words "sneeze" and "satiation" — is defined as an uncontrollable sneezing fit that occurs as a result of stomach expansion from overeating.

There are not many articles published on subject, but did find two helpful articles:

Have you tried eating smaller meals to see if it helps?

Hello! I had a sleeve 8 yrs ago and this just started happening to me. I agree it's super frustrating and people do stare. The intense need to blow the nose is awful too. Plus, the added mucus drip makes my stomach feel worse.
I never knew this was a thing. I'm wondering why this has just started now? I didn't even eat half a peanut butter toast and started sneezing - at a measured and steady pace. It's not "uncontrollable sneezes" it's a very odd "reactive sneeze" that is about 10 minimum and then I lose count.

I had an old-school Gastroplasty back in 1982. Every time I get full, I always sneeze (anywhere from 4 times to 6 times in rapid succession). I also hiccup, but less frequently. I always have a kleenex with me when I eat. I'm glad to know I am not alone.
