fwiw; I had unexplained anxiety, fatigue, poor sleep and cognitive decline as a post-COVID induced histamine intolerance with a few bonus attributes. High amounts of histamine would accumulate in my mast cells then get released in 3-5am, undermining sleep and also inhibiting serotonin.

It took me about four years to fully understand my condition. Hope you figure out what is bothering you. The body is incredibly complex.

My gf experiences some thing like this sometimes. Seems to correlate without exercise or excitement or eating histamine rich food. She takes pentatop to regulate it with some success. I'm also interested to head about your experience.

How did you figure this one out and how did you resolve it? Asking for ME!

How did you figure this one out and how did you resolve it? Asking for a friend!

What did you do about this? Is it at all related to allergy levels? How do you measure your histamine level on a daily basis?
