FWIW, my own gout flareups seem to be related to times when I've fallen off of the wagon. I also have migraines when I take the medication for it, so I can't take that.

Instead, I hydrate like crazy. I drink water whenever I think of it. I also take some of the unsweetened cherry juice that someone recommended above in some of my water. (Eating cherries would also work. Use your best judgement regarding your carb/sugar intake)
