Flonase. HEPA air cleaners will help a good deal. Benedryl and now the over the counter version of claritan at Wal-Mart will also help. Frequent showers to get the pollen out of your hair. All of these will help. I always keep one of those saline spray bottles handy. And I use those breath-rite strips at night as I have a deviated septum.
the saline solution in post #2 does work--may take a day or two so use in combination with something else and then stay with it
You need to find a beekeeper in your area and get some bee pollen from him. It will contain all the stuff that is making you have the allergies.
A few weeks before allergy season start taking a granuale a day for a week, then increase it to two for a week, then three, etc etc.
It works on the same principle as a snake bite. If a snake handler takes a little bit of snake venom at a time he builds up antibodies. Come to think of it it works for lots of things like smallpox?
