I'm allergic to a large number of things including dust, some deos and perfumes, chalk powder, even vicks inhalers and lots of other things. I even get allergy attacks during change of seasons. This time it's been almost a week and my allegy is showing no signs of relenting. The old medicines don't seem to work. I have been sneezing non-stop for 2 hours and it's driving me crazy. I coujdn't pay attention in class at all. Does anyone have any suggestions ?
