Get some beano. Follow the directions in it. It works when used properly.
Chew thoroughly before swallowing. Thoroughly as in you can't chew it any longer..thoroughly dissolved. IT's the bigger pieces that don't get chewed totally that cause more gas. This can happen when eating in a hurry.
Some say not to drink any liquid while eating, but some say to drink water with your fiber. It helps it all go through more smoothly and hopefully out faster.
Now if the gas still doesn't go away,,,it can come in handy when trying to repel someone like solicitors at your door.
I find that if a smoker sits down by me in a casino, if their smoke blows my way..guess what blows their way?
