I feel your pain on the allergies... even in the winter the dust really gets to me.
Clairitin OTC non-drowsy is awesome!! It used to be available only by perscription, but now you can get it OTC (hence the name). It competely dries up your sinuses, but there is absolutely no drowsiness. I use it when i have an exam/theater/race and can't fall asleep, and zyrtec (since it's covered by insurance and makes you drowsy) all the other days.
hope you feel better! at least it's above 30 in Cali (lucky!)
