try mucinex d instead, that works better for me than Claritin D, I also use vicks vapor rub wait until it is good and “burning” then take a really long hot shower (or put your head over steam with a towel.

Don’t do the steam thing, because that only (to me) makes me way more congested. I don’t take claritin, it doesn’t work. Zrytec works better and try going to the doctor and ask them about Nasonex, I use that nasal spray, zrytec, and singulair every night, and I rarely have a stuffy nose now.

Try using a netty pot — it was on Oprah. It helps relieve sinus congestion. Something that is similar but works even a bit better (though its less comfortable), is a salt-water snuff. Basically you get some water in your hand and put a bit of salt in it and then sniff it up your nose. It’ll help clear things out.
