I'm in the same boat as you mate and have been for last 10 years or so!
Love summer - hate hayfever!
I get it pretty bad, sneezes, blocked and runny nose, puffy eyes, the lot. Normally hits me around April, but been a bit delayed this year and only really hit me hard last week.
I take the one-a-day pills, but I don't follow their instructions I'm currently taking them 3 times a day combined with Pirinase nasal spray twice a day (suggested dosage is once daily).
It's just about keeping it at bay for me and I'll continue it like this as long as it keeps it under control.
