Benadryl is effective for my sinuses. Sometimes I only need half of one of those pink pills to do the job.
Benadryl is an antihistamine.
Histamines cause inflamation.
Inflammation causes obstruction.
Obstruction causes apnea.
Thus Benadryl works.
The gastrin cells in the lin8ng of the stomach regulate the parietal cells in the fundus of the stomach to release stomach acid and intrinsic factor.
This is done by the g-cells releasing histamines into the bloodstream.
If you notice that you get congested after eating, that is a histamine response.
Solution- Do not eat for several hours before sleeping.
I sleep much better on an empty stomach.
