I Have Epigastric Irrigation With Burping And Indigestion When I

I have epigastric irrigation with burping and indigestion when I take Clonazepam. Thought it was a coincidence, but it has happened with Xanax too. What should I do. I take Ranitadine from history of gerd, no problems there for months, but it doesn't seem to do anything about this. Provider suggested taking Prilosec which helps a little. Any suggestions appreciated. Thank you.
