Having battled with Gout for many years now, I have found there can be very limited correlation between attacks and specific behaviors. Sometimes flares just happen. They can be less intense, shorter, and rarer while on Uloric or Alopurinol (sp?), but nothing guarantees no flares for us with the missing enzymes. If your uric acid level in your blood did not go up, they correlation may be hard to document or not even consistent.
I have this personal theory that changes in routine can give the crystals the window they need to get to painful levels.
I will keep an eye on this thread for better information that my observations.
