What’s going on
The hypothalamus (your temperature center) needs time to adapt when estradiol increases again.
Estrogen can briefly raise histamine, causing warmth, restlessness, or sleep disruption.
What helps
Give it time: Usually improves in 2–4 weeks.
Morning use of Oestra® or a short course of a gentle antihistamine can ease the transition.
Protein ~100 g/day for steady estrogen metabolism and neurotransmitters.
Methylated B‑vitamins + iodine may smooth the process.
Bottom line: Temporary flares are a sign your system is responding—not that something is wrong.
