Allergy Season Returns

It's that time of year when my seasonal allergies return. I'm severely allergic to ragweed, and the peek of the season runs from mid August through the first fall freeze. About two weeks ago, I got my Allegra prescription renewed and have been faithfully taking it every day. Even though the pollen count has been high over the last several days, I've not had a single symptom yet. I know the drug works, but just think the density probably isn't high enough to affect me just yet. Usually on days that I have to be outdoors, it gets very bad. time will tell, but I'm sure in another couple of weeks, I'll start to feel a little worse.
