Thanks for your reply. I have taken Gas-x before without problem. But over the weekend I was away, I ate very very little cuz I was afraid of having an episode. Perhaps not eating when you have IBS...
I have had IBS since I was a teenager - I'm now grandma. That's a lot of years! Recently, I went on a weekend vacation. I was afraid I would have IBS difficulties, so I took gas-x twice each day....
