@lsk1000 yes, thank you. Gas-X works well, but you really have to time things properly. I used them for a while and didn't think they worked, as I would take 1 or 2 and would almost immediately start passing gas. The active ingredient Simethicone, actually allows all the little gas bubbles in your digestive system to create a large bubble which makes it easier to pass the gas you have accumulated. You need to give them some time to work. So, not to be taken right before getting on an airplane or attending a social function, which is how I initially started using them. :-(( I will take one after my dinner and before bedtime during treatment.
