I have IBS and find that it is anxiety and lack of sleep that triggers mine.

Back in the days where I had IBS attacks everyday I took Inner Helath Plus everyday which I think did help and I took Mintec on bad flare up days and it worked wonders. Another thing that really helped with the pain was Aloe Vera Juice, you take a tablespoon 3 times a day and it really settled my guts down.
