As a chronic allergy sufferer I have spent my whole life trying out various allergy meds. Last weekend I put everything I had to the test as I spent most of each day sorting through dusty farm crap in dusty barns and outbuildings. And I found a combination of meds that really did the trick, so I thought I would share. It is made up of two important components:
2. Claritin/Allegra/Zyrtec (your choice)
Take the Benedryl by night (this is key; Benedryl by day is no fun) then take the other med (Clalritin/Allegra/Zyrtec) first thing in the morning (whichever you prefer, I've listed them in increasing strength). I'm no doctor (or at least not an MD kind of doctor) so I have no idea if this is an allowed drug combination - at the very least I wouldn't recommend doing this long-term. And I'm not really recommending it - please don't sue me if you try it and die. But when faced with some acute allergens it certainly was my savior. I used a half-dose of the Benedryl and an over-the-counter Claritin and was happy as a clam. I kept taking the Benedryl for the next few nights after I got back from the farm and never had any residual allergies either. What a deal!!
