the only thing Gas-X ever did to me was give me more gas.
acidophilis... that's what you need.
when i stop taking it for a couple of days and eat a lot of simple sugars... man, the gas is horrible and really smelly.
what made me so sure it worked on me is that when i take anti-biotics, the gas comes back and it gets bad.
but with acidophilis, even if i had some gas, it doesn't smell at all!
add some fybogel to that (psyllium), once or twice a day, and you got a winning combination for getting rid of gas and having 30 seconds clean shits! LOL
