I love Claritin D because it helps me survive the spring season in this area.  I never suffered from allergies until nearing 40 - but every spring now the cottonwood trees blowing what looks like snow in our backyard makes me ill.  Claritin helps me cope and not be so fuzzy.  I also recommend it to friends and family who seem to suffer the same every spring.  I hate the feeling that Benedryl or other products give me - they act like a sleeping pill to me - and heaven forbid I attempt to take them and work or drive!  But Claritin takes the "fuzziness" and stuffiness away without making me dull...
