Suggest Treatment For Gerd And Vomiting

I have had gerd since 1987. did not take rx s until 2000. have been on nexium and all the others since. even with the meds I get reflux nearly every night. up until a year ago I threw up several times a week. it was always dry heaves and so scary because I thought I was going to gag and die. I started a year ago fighting this nightly nausea. I have tried everything. Lately I am using alka seltzer chews. sometimes helps and if not I soak crackers in milk. I have not let it make me throw up for nearly a year, but the getting sick part is still awful. It s a fight and it is always after I take my meds. (amitryptelene and sertraline) A few months ago I had a test and was told I had Barrets Esophagus. I went to my family doc and all he told me was he had only seen one person die from it and that was just because they did not care. I am using aloe in my juicing and I mix it with my juices. I also add yogurt and ginger. This is so stressful and worrysome. Is there anything else I should be doing. I am 67 yrs old and about 40 pounds over weight. I am a widow and live alone. I will take any suggestions seriously.
