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. Then on the Monday I returned, I had explosive diarhea. I did not make it to the bathroom. The diarhea was greenish in color and I immediately thought of the little green gas-x pills I had been taking. Has anybody experienced this as an after-effect of taking Gas-X? This has never happened to me before, and now I am afraid to go out anywhere just in case it happens again. Needless to say, i will not take gas-x anymore. Do you think it was the Gas-x or is this yet another IBS difficulty I will have to deal with?
