Allergies

[Terrabon98]

I get very bad allergies in the fall due to ragweed (I think). For the past few years, I have taken allegra so that I could actually have a life during this period. But for some reason, even with the allegra, my allergies have just been out of control this year. I live on a college campus in an old house, so it could be that the house is old/dusty, etc. My main problem is when I go to sleep, I literally can't breathe through my nose and I stay awake...anyone have any suggestions of anything I can do to ease the situation a bit?
