Anyone know of a way to combat frequent gas?

I've tried beano. I've tried some natural 'supplement' gas relief daily thing I found at Rite Aid once. I've trid gas-x or maalox + gas relief afterwards. But nothing ever seems to work.

I always get worse when I start eating better (more veggies, more fiber). But everyone tells me "oh, it will go away when you keep eating this way for a long time." Well...it doesn't go away. I'm always this bad. And of course it's worse when I drink soda, or when I have dairy products or veggies like broccoli, cabbage, asparagus, and of course beans.

It can be rather embarrassing sometimes. I try to control it the best I can but sometimes you just can't!

Any suggestions?!
