Gout, as you know, has a very strong hereditary component to it. If you read everything on the internet about how to get this disease under control you will become very frustrated and feel "painted into a corner" as far as dietary restrictions are concerned - no beer but also no whole grains or beans? No cheese? No coffee???
First of all, I don't know how long the OP has been on allopurinol, but it can take a long time (many months) to have the desired effect, and so it's important for the prescribing doctor to communicate these expectations. During that period of clearance of the uric acid through the kidneys with the use of allopurinol, you might need to stay on a low-dose therapy of one 0.6 mg of colchicine a day to keep the attacks at bay. For more acute attacks the use of a "medrol dosepak" is extremely helpful - it's a tapering regimen of methylprednisolone, a steroid pill, that can knock out an attack without the use of a cortisone injection. But this treatment can not be used frequently.
If the allopurinol fails after 6-8 months of usage, then there is a brand-name medication called Uloric which can be used instead.
As far as supplements are concerned, cherry juice is known to help, but there is also this stuff called "Acid Drainage" capsules by ph Ion that I've known several people to take and have had quite good results. You have to stay on it, just like you'd have to stay on allopurinol, but whatever works so your quality of life is as good as possible. What I mean by "quality of life" is that there are so many things you can sacrifice for the sake of gout eradication before you want to put a gun in your mouth.
Lastly, what I can add is that gout is by definition a high concentration of uric acid in your body, so to decrease that concentration is your ultimate goal - so drinking more water during the day is essential to your goal as well. And you might have to be aggressive in changes to your behavior at first, but then slowly add items back in after your condition is under control.
