I’ve had intermittent nausea and vomiting for several years. I never know what sets it off. I’ve had several tests to rule out gallbladder disease and they have all been negative. My daughter in law had her gallbladder removed after experiencing similar symptoms. Her surgeon told her to take Ox bile which is an over the counter digestive aid. I get mine on Amazon and take it twice daily. So far I have not had an episode of nausea and vomiting for 1 yr.
