Perhaps you could form a band with other gas producers.

Gzboli comments:
No, do not stop eating.  Learn to fart silently with a cherubic smile
on  your face when someone in your presence expresses bigotry,
insolence,  or intolerance.  This is a little appreciated and much
under-practiced form of social comentary.  Enjoy.

Try this for a couple of weeks:

Give up all dairy, fruit, and things made from grains (and probably
potatoes),
Restrict your legumes to lentils, (split) peas, and adzuki beans - and
have a smallish serve or two per day.

If this settles the gas, then slowly introduce other things back over
a few months and see what you can get away with.

Let us know how you go.
