@mikejjb123, I can certainly understand your frustration with gerds and colitis, definitely not a happy experience for you.. I am assuming that you have been to the doctor because you mentioned gerds and colitis. I get these symptoms on and off depending on my stress levels which sets them off, it’s usually treated with medication and dietary changes. I don’t know if it’s related to autoimmune disease but perhaps your doctor can help with that, as for the nausea, it comes with the other symptoms but there’s OTC medication for that like Gravol, best wishes.
