Oh my god YES. the last couple of weeks have been awful. My tummy feels like it is cramping up but it's actually gas in my stomach. I get in fetal position like i use to when i got period pain and it would all come out then. It really hurts if you don't let it out so as the saying goes better out than in. If i am somewhere where there are heaps of people i just walk to where no one is let it out and procceed to do what it is i was doing before hand.
Happymum2 - LOL about it lasting a whole aisle in the supermarket, i reckon some of mine could too.
