Are Histamine surges affecting your sleep?

Histamine surges at abt 2-3 AM. This could be a reason many people wake up and have difficulty falling asleep .
I researched and found an antihistamine - Zyrtec - subdues this histamine surge and I sleep 7-8 hrs.
So many people on useless or habit forming drugs because docs are
not interested in pursuing a more natural approach.
I don’t advise -I only pass on my experience.
I only take a blood pressure med .
