I've been using a nasal steroid spray year 'round for almost 7 years with no significant issues (although I'm on Rhinocort, not Nasacort) - definitely try the Zyrtec, it seems to work much better than Claritin.

Ever since the antihistamines went OTC, I have not had much success with them, even though I take Claritin daily. Allegra used to work the best for me, but the cost of the prescription vs. OTC has steered me away. I also use Nasacort, and just recently started taking Singulair at night. My allergies are fine during the day, but I know that I do snore at night, so I'm wondering what the next step is. This past spring allergy season was really hard to deal with, so I'm thinking of going back to an allergist for treatment. Does anyone have any suggestions on the snoring thing?
