This might be an odd question for this thread, but does anyone else find that allergy medications make anxiety worse? It's been a few times now that I've taken half a Zyrtec and not only does it still knock me on my ass, but I wake up from these involuntary naps several times in a complete panic, heart pounding in my ears and everything. And then I'm jumpy for the whole day. I'm just wondering if anyone has had similar experiences, or if my theory is way off-base.
