I have been suffering with nausea for years, literally years. Have been put on prevacid and others with no or very little help. I had my gall bladder removed in 2007 (polyps found on ultra-sound) and it didn t help with my stomach. I am currently taking twice a day prevacid 30mg. I am a 55 year old woman, don t smoke, and rarely drink. Sometimes when I get nauseous I sneeze . I belch ALL THE TIME!. Yesterday my stomach was so bad I actually was over the toilet, but only burping, loudly! I had to lay down I was so sick. I have had colonoscopy s and scopes of my stomach. First time showed gerd... and I haven t felt good since. I am taking tamoxifen for breast cancer . Any other ideas for me? I am so sick of feeling sick.
