I previously took Cetirizine Hydrochloride (ZIRTEK), but this year I was suffering pretty bad, so I swapped to Boots own Loratadine tablets and am doing much better.
I think changing your medication often is the answer, think maybe you get tolerant to some?
Also ordered a Neti pot after recommednations on here. Arrived this morning, almost pissed myself when I saw the size of it!!! The pics on amazon make it look quite compact. I have seen smaller watering cans. havnt tried it yet though.
Also using beconase nose spray for when it gets bad and optrex havfever eye drops.
Got Haymax, nose stuff but its a load of nonsense!!
Also some olbas oil on the pillow at night helps get a good nights sleep, aswell as changing your bedsheets often and keeping your bedroom as dust free as possible!
