Odd! I've had hayfever since I was 13ish (now 39) and it's not as bad this year as it usually is - yet.
I find that treating symptomatically works better than prescription antihistamines. i.e. nasal spray to stop the drippy nose and optrex type stuff for itchy eyes. I find that antihistamines just make me feel bunged up and lethargic.
