you might search on lowhistaminechef for natural alternatives. I've had excellent results from rutin and quercetin for antihistamine, royal jelly for mast cell stabilizing. And when I quit low dose Klonopin for sleep, due to intolerance, I found pituitary glandular did the trick.
Thank you. I had a negative reaction to quercetin, but I don't remember what exactly, and I don't remember the dosage. I will look up the other supplements you mention. Compared to a lot of people my sleep is not bad. The post-nasal drip ("drip" hardly seems an adequate term) can be bad enough to wake me up. Like all other symptoms, it is worse, following increased activity. At times I've wondered if it is a fungal infection -- and an allergic reaction to the fungus? I could live to be 100 (I hope not) and never figure this out.
In the late 90s a doctor prescribed Claritan. It's supposed to be non-drowsy, but it made me very drowsy, all day. I didn't refill the prescription. I was thinking I might, because it is now over-the-counter, try it again, a small dose at night.
Or do nothing.
