Also it sounds like your trying way too much at once, slow down. Kiefer, pepto bismol, the wafers, etc. All of this could cause you mord problems, I suggest cutting things out one by one until you reach a desired state (your always going to have gas, and without the extra 5 ft of your digestive tract (colon) there is no where for it to go besides out. Also Beano contains Sorbitol which causes gas and Gas X is innefective at stopping gas production It is also known as Simethicone which only breaks up small gas bubbles into larger ones which are easier to pass. Again focus less on what can stop the gas and focus on what is causing it. Again I have been suffering from extreme gas for nearly 2 years, if you can think of it I have probably tried it. I relieve my gas by laying on my stomach or getting on all fours, try it out it does wonders for me especially after a hot bath.
