I have recovered from the headache and am back about where I was before on the histamine intolerance. That is, I am recovering slowly. I clearly over-did it with the rotisserie hotdog. But I learned a lot! For example, I learned that all that noise in my ears is from the vasodilation impinging on my cranial nerves, which are close to my ears. The reason it gets so bad as soon as I lay down (and at night) is that it alters the blood flow in that region and the blood vessels relax further, making everything worse.

Since I have such an acute an obvious case of histamine intolerance, I have done a lot of research and made a lot of observations that could help others: One important area is regarding the lists of foods. It's known (and also an active area of actual medical research) that histamine intolerant people report reactions to a wide range foods, many of which do not actually have histamine in them. Well, I have solved that puzzle: The main effect of histamine in the body is to provoke vasodilation (through nitric oxide). If you eat something with histamine in it (and you are histamine intolerant) you will get that vasodilation. If you then consume ANOTHER VASODILATOR, that will worsen the symptoms. A great many healthy foods are natural vasodilators, and appear on lists of non-histamine foods causing reactions.

I found that if I avoided the foods that actually have histamine in them I did not get the vasodilation. Then I could eat the other foods! I greatly expanded my diet that way.

Hope this helps anyone else struggling with this.
