I have just tried your dads recommendation and it works, please say a big cheers to him from me.
I got a glass tumbler and filled it 1/4 Brandy and 1/4 Port and the other half was boiled water, took a big swig and within a couple of minuets up came a big load of gas, good thing about it it also it goes to your head and makes you feel much better which helps with the pain.
