Erm. I have read a very good "bowel" book which says that although it is embarrassing flatulence at least shows that there is movement which always a good thing in the digestive tract. I can recommend a visit to a health food shop and try some of their remedies. Prebio 7 is excellent and is recommended to be taken if you have had a course of antibiotics. Take a whole course (read the instructions) and you will be amazed by the difference. There are cheaper capsules on the market but I have read that quality is all important because thousands of the live bits in them do not survive the stomach and therefore you need to have millions. Sorry about the product placement but I have found this item to be really good.
