Clarinex & Clarinex-D

Maybe it is too early to tell for sure, because I've only taken these prescription versions of Claritin a couple of times.

Clarinex - OK, but nothing fabulous. I stay congested, but not too much.

Clarinex-D - Not great. Too aggressive at first, then too little oomph later on. Plus, I tend to wake up from it strung out, dehydrated. Ugh.

For the long haul, Clarinex (or maybe its OTC counterpart) is looking like a good possibility. Whatever else is true, I drink water like mad.
