It's amazing how little it can take to upset the system, and how long it can take to set it right. Once irritable bowels are diagnosed and the doctor is convinced it's not cancer you are sort of on your own, trying whatever to get rid of it, not knowing if there is a cause or a cure. (it might all be in the mind)
I've tried various variations on what i eat, used lactace, probiotic, taken up walking, and given up a really irregular job hoping it would help. A bit disappointing it was as simple as it turned out to be in the end, but happy to be better.
Main reason for sharing all this is hope that it might help someone else. I had never thought of the possibility that hot drinks would be stopping my bowels from getting better.
