For all those who suffer from hay fever and don't use a nasal spray of any sort... start using one !
I suffered from terrible hay fever, it completely knackered me. I used to play a lot of golf and sometimes in the height of summer I'd have to walk off mid-round purely due to hay fever. I'd feel really weak and start shaking and sweating and my nose used to bleed constantly.
I tried various tablets and eye drops and they helped but never really enough. As soon as I started using a nose spray I was 10 times better. As other folks have said, it does give you a pretty nasty taste in the back of your throat but you soon get used to it.
The problem is most folk don't start taking anything until their eyes are burning and they're sneezing like mad. My doc told me to start taking all my stuff in early spring so that I had a level of protection in my system and it's been good advice.
My girlfriend has always suffered from pretty bad hay fever too and this is the first year she's taken a nasal spray for it and she's totally fine. Well, hay fever wise anyway...
