Gas, farts, flatulence....

I take Attune bars because it's an excuse to eat chocolate.

The good probiotics have to be refrigerated IME.

At the first hint of killer gas, I take 2 Gas-X tablets.  I also find that this killer gas happens the night before I am going to have a "cleansing" BM -  you know what I mean, the kind you write home about.  So I will take 2 tablets of a stool softener before bed to get the process moving along. 

It helps that I have a very understanding hubby who says he wouldn't trade my sexy new body for a fart-free fatty.  Well, he doesn't say it exactly like that, but that's the gist of it.  And it strangely does make me feel better. 

I use Natrens Healthy trinity probiotics, expensive but worth it IMO. Its a capsule thats refrigerated and found at some health food stores or can be ordered online.
This helped me tremendously when I had c diff, and have taken daily since then.
