I get more wind from both ends now than I did before I am sure of it, in fact I fart that much more now that if fart's were oxygen you could shut me in an air tight container and I would still survive pretty much the same for the burps too
though I find I get the burps more if I have had one of those days where I have felt a bit rough (e.g today) and then don't eat the following day (e.g what I will do tomorrow) so you can bet your life by this time tomorrow I will be burping like a 10 piece brass band
