What works best for me (and I've been bloating up with gas for lets see, um, 30 years??!! Yikes) is Gas-X or Phazyme anti-gas caplets. Also sold as store brands like RiteAid. You'll find it near the antacids. Other people will have lots of other suggestions because everybody's different. But I sure wish I'd found Gas-X thirty years ago!! Just take two before you leave the house.
