Gas can be very painful for me. I have sensitive intestines and can suffer when its only a small amount of gas. it can literally bend me over in tears. I have gone to the ER thinking my guts were ripping.

my mom is a public tooter. esp if she is in line and you are standing too close to her. She will let it fly. or she will hack and cough right on you. She once said "did you know my TB test came back positive?!" as she turned to hack and cough on a lady who was bumping her with the shopping cart.

One other suggestion... have you been eating anything with sorbitol as the sweetner? Things like sugar-free candy or gum? Those give me trouble if I over indulge or use too often.
