Try peppermint - it is a tasty way to relieve gas, nausea, and
stomach pain due to an irritable bowel, intestinal
cramps, or indigestion. And for the pain you can try camomille. My doctor advised me to have Duspatalin 200mg capsules. I really felt better after having taking this medicine. Less flatulence ,basically no gas ,no more abdominal cramps ,no more constipation that's what i experienced. Duspatalin is actually administered to sufferers of IBS.
