You should try a Neti Pot, Rafini. It's an ancient method of nasal irrigation. It uses warm salt water to clear out and neutralize the allergens in your nasal passages. It takes a little while to get the technique down, but it certainly works. Best thing is it's dirt cheap, totally safe, and you can use it as often as you like.
I get bad hay fever in the spring, but since I started using a Neti Pot earlier this year, I haven't had to resort to anti-histamines once. [ Jeez, almost sounds like a promo ad! .]
There are several hubs about it. Look it up.
