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 or sleepy and I can actually function. I don't know how I would make it through this season without this product! The fact that I only have to take it once a day it also another plus for me - who can remember to keep track of doses,... in this day and age? I can also purchase it over the counter and at all local stores - from drug stores, supermarkets or Walmart! And best of all it actually works! The only drawback I have found is that I can find a generic product for much less - so I am prone to buy the generic product - and I find that it works as well also.
