I'm just allergic to everything

After trying nearly everything under the sun to help my allergies, I saw something at Walmart that I hadn't tried before.  So I bought a box of Alavert.  It promised 24 hour non-drowsy relief from allergy symptoms.

After I took it, my sneezing and itchy throat ceased.... for about ten minutes.  Then, as usual, my body said, "Ha, nice try, I don't think so" and I began sneezing once again.  Several hours later, I'm sitting here with my symptoms as bad as they always are, as if I hadn't taken a single thing.

You know, it doesn't surprise me.  I've tried Allegra, Claritin, Zyrtec, Benadryl, Advil Allergy, ChlorTrimeton, etc.  Nothing besides Benadryl works, and that stuff puts me out.  I took some on Friday- thank god Hubby was home because I fell asleep from 1pm to 4pm!!  So if I want to be conscious and able to function, I won't take Benadryl.

I suppose it would help if I knew what I was allergic to.  I know that grass pollen does it for me.  So does tree pollen, so pretty much anything green that grows outside.  Yeah, that sucks.  Fortunately, I don't have any food allergies, but I am allergic to pregnancy hormones, apparently.  Oh, and sunscreen... yeah, that sucks, too.  Oh, and most over-the-counter facial moisturizers (btw, the Clinique line is awesome, I love it).

Anyway, it doesn't matter at this point what makes me sneeze or drip from my nose or burn my skin or whatever.  What matters is I'm friggin sick of it!!  Does anyone have any advice or know of anything that I haven't tried??  I'm getting desperate.  Snotty, sniffling, watery eyes desperate.  Help!
