Try European cheeses. Many people have a sensitivity to A1 milk (USA) and not A2 milk (Europe, Africa, Australia). It seems there is a mutation in one of the amino acids in A1 milk that make it a histidine instead of proline. Histidine turns into histimine which is what some take antihistamines to alleviate. I don't know if it works for tinnitus, but it might be worth a try for you.
