I've been using Allopurinol for years, but that in itself isn't good I'd guess? If, and it is likely, my change in diet or changes in my body have lessened the risk them I could be taking it for nothing?
Don't eat any processed foods or anything with preservatives or flavour enhancers such as Chinese Takeaway Food (full of MSG), offal, mushrooms (don't ask me why), asparagus, wine, anchovies and shell fish and beer! (Other than that have a ball!)
Plenty of water, cherry juice and allopurinol
