Hi. 30 yrs is a long time to be suffering so. Not sure what tablets you have used and it's difficult to give advice to someone who has had it for such a long time! You must be an expert by now, surely?I use peppermint oil capsules before every meal if it gets very bad. I always keep them with me! Over the last couple of weeks though, I have found that by consuming less food, I am actually soooooooo much better - not perfect - but far far better.
