Last year was the first time I'd really suffered with Hayfever and hit hit me like a tonne of bricks out of the blue one morning. It was f@cking awful. I use Cetirizine Hydrochloride, which is what Piriteze is - Sainsburys do the same stuff for £1 rather than the £3-£4+ Piriteze charge, they contain exactly the same chemicals and do exactly the same thing. The tablets are even the same shape.
