Hormones were the last piece, not the first problem

For years my symptoms had a rhythm I refused to see. The flushing, the insomnia, the pressure headaches — they clustered in the same eight or nine days every month, and I kept blaming whatever I had eaten.

The loop

Estrogen encourages mast cells to release histamine. Histamine, in turn, nudges the ovaries toward more estrogen. Progesterone helps stabilize mast cells and support the enzyme that breaks histamine down. So a cycle with strong estrogen and thin progesterone is a cycle where the bucket fills faster and drains slower. That is not a moral failing or a food mistake. It is a feedback loop with a calendar.

I stopped asking what I did wrong on the bad days and started asking where I was in my cycle.

What actually moved the needle

• Eating enough. Under-eating was quietly suppressing ovulation, which meant less progesterone, which meant worse histamine weeks.
• Protein at breakfast within an hour of waking, which flattened the afternoon crashes.
• Backing off intense training in the luteal phase and walking instead.
• Tracking basal temperature for three months so I could actually see whether I was ovulating.
• Treating light and sleep like medication, not lifestyle.

Nothing here was exotic. That is sort of the point. Once the mold exposure was gone and my gut had stopped being on fire, my hormones needed food, rest, and time, not another bottle.
