Zyrtec D/Claritin D
Or you can keep taking your current Zyrtec and get the Sudafed from behind the counter(pseudoephidrine-the 'new' kind doesn't do squat).
I feel for ya! BTDT I'm sure last fall had chronic sinus infection/irritation. Could not breathe thru my nose, it was so bad! My allergist recommended Afrin, for use for 1 week, and ordered me not to use it further than that because of it's addictive nature. I still have it...never did use the stuff, because I was afraid of a more-horrible rebound effect.
