I was having horriable gas pains, and had gone through 2 boxes of GasX with no luck. I went to the health food store and they gave me a bottle of (i hope I am selling it right) Acidoldolyfs Probiotic. I took 2 tbs the evening I purchased it and 2 more the next morning and all of my gas was gone. It was the best purchase I have ever made and was blue berry flavored to boot!:clap2:
