I have a couple of ideas that are really cheap and easy to implement that have made a huge difference. One is that I rinse out my nose, essentially use a neti pot, every night before I go to bed. The goal here is to get all of the pollen out of my nose before I sleep. I also take a shower and wash my hair every night. This one took me a long time to get into, because at first it sucks. But the truth is that the pollen gets into your hair and when you sleep it is like sleeping in a bush of ragweed, or whatever you are allergic to. In the morning I just rinse my hair and style as normal. After I got used to it I figured out that it actually saves me about 10 minutes in the morning.
I hope these ideas help.
