are you allergic to dust mites? if you are get a vacuuam with a special filter in it and used it on your mattress. wash your pillow cases at least once a week. dust with a special item that picks up all dust not just making it float in the air. they have hyperallergenic pillow and mattress covers that prevent dust mites. now if you allergic to just dust from like the roads and fields, that is harder to recommend things for you. i would suggest a daily antihistimine, zyrtec, allegra, or clairitin. these are non drowsy antihistamines. the best of cours is benedry or chlortrimaton but these can make you really drowsy. hope i helped a little.
