I have periodic gagging. This happens at various times of day and night. I know I am not pregnant, but may have the return of an ulcer, although the pain is not anywhere near what I experienced in the past from an ulcer. The gagging comes on unexpectedly sometimes a bit after I have eaten, but most of the time just randomly and not associated with food or drink. At night most of the time I wake with a horrible nausea wishing I could throw up more than actual gagging. The gagging is not just a small gag, it brings tears to my eyes and I have to stop what I am doing to get it under control. The only medication I am on is a Murena IUD. Occasional Ibuprophen or acetamenophine (rarely). Any thoughts?
