I have had IBS for many years but have never had the nausea I am having now! No vomiting and never diarrhea ! Bloating,gas,nausea and weak feeling ! Lower intestinal soreness. Sore place under right rib cage sometimes. Burning stomach, feels better when I eat but then very full feeling and nausea after ! Taking Omeprazole 40 in the mornings with Cutrelle probiotics. Triazolam .25 at bedtime.
