I've had the same problem on and off my entire life. Do NOT drink extra coffee like the person above me said. Coffee contains tanic acid, which irritates the lining of your stomach and can cause diarrhea. You don't get"over it"like they said. It just irritates your stomach more and more.A natural remedy would be peppermint. You can find the essential oil of peppermint at any natural foods store. Put a few drops up to a spoonful into some herbal tea and drink it. Avoid coffee&carbonated drinks as they're irritating. If you need caffeine to wake up in the morning, try green tea. It's not great on a stomach but much softer on it than coffee.Licorice (black, not red) is also a remedy for upset stomach&diarrhea in general. You can find licorice tea at most stores.There's a really strong natural tea that will calm you down for those moments you get anxious - it's Valerian root, also found at natural food stores. It doesn't smell good (my husband won't even let me keep it in the house but I don't think it's THAT bad
but it really does have a calming effect when drank as a hot tea.Get Fiber One on your cereal isle and put that on top of whatever cereal you eat. Fiber balances you out - helps bind you if you have diarrhea or help you go if you can't. Eat a healthy diet with plenty of greens for natural fiber.I bought something called"Colon Cleanse"online for like $90, but I never used it b/c my IBS cleared up before it arrived, but I think the main ingredient in it is just fiber... I know what you're going through - I had IBS straight for 2 years once! UG! (before I found natural remedies)
