Thanks for the tip Bazza.. but.
I've tried all the so-called remedies.. Milk of Magnesia, Andrews salts, Eno's, Gaviscon etc. all to no avail..
the only substance which comes close to a cure is neat bicarbonate of soda.. admittedly, the flatulence produced by said remedy might be excessive, but if one has an interest the aerial manouvers of flying a kite, the benefits are twofold, inasmuch one is able to maintain maximum height on the kite whilst keeping one's company entertained at your garden party, barbeque, or shindig.
