Hey, i do suffer from hayfever quite bad too along with other allergies.

I've taken all types of pills with the differnt chemicals. My doctor always told me to find the right one.
I even tried putting this vaseline type substance around my nose from boots which claims to stop pollen entering the nasal passage.

In the end the best result i have found it using the nasal sprat beconase, you have to stick to the schedule twice a day for like the first week before it takes affect then once a day is fine.
Ever since i have been much better
