I'm allergic to everything. I find over time, the allergies get worse. I moved 1,000 KM's from where I was before, for warmer weather, and I had no allergies for a year or two.

They gradually just got worse as I built up a reaction to them I guess.

I find Zyrtec makes me a bit wired .. not a bad thing, but I prefer to just ride it out. I generally find taking a nice hot shower to steam the hell out of everything works great as well.

I do find that allergies and PSEUDO RELAPSES can go hand in hand however, I cannot really vouch that an allergy has caused an attack.

However mine always seem to happen like clockwork in (Australia's) spring - between Oct - early Dec I'm waiting for it to happen. =)
