Hi, like I mentioned, the nausea could be a side effect of
pepto bismol. Probiotics contain good bacteria and help
with digestion. And Prebiotics are nondigestible carbohydrates that act as food for probiotics. Probiotics are found in foods such as yogurt, while prebiotics are found in whole grains, bananas, onions, garlic, honey and artichokes. A combination of two in a healthy diet is beneficial. Try this. Regards.
