Gallbladder and the Nauseous Sneeze

i had my gallbladder removed in 2010 and this nausea and sneezing began in 2016, so no relation to gallstones. I start to get nauseous and feel like I might need to throw up, then I sneeze and am fine. It doesn’t happen daily or on any regular schedule. I hadn’t paid a whole lot of attention to time of day or whether I have eaten or not until recently. The last few times that it’s happened is in the morning before eating. I will continue to monitor time of day and whether or not I have or haven’t eaten. If anyone figures out the reason, I would be so happy to hear what causes this.
