The BEST product on the market is Devrom. My husband started using it about two years ago BEST thing for our marriage. I was seriously not able to even go in the room at night because my eyes would water!!! Now as long as he takes it morning and night we have no problem
He still has the gas just no smell. These were developed for colostomy patients so that the bag would not have the strong smell. I forget the ingredient but my husband is a chemist and says its safe. Also it helps that he likes the taste.
