I no longer get hayfever because I have a cancer which works against my immune system, it's been really lovely not having hay-fever and being able to enjoy outside life and smelling flowers at this time of the year for the first time in my life. My anti hayfever routine was: take anti histamine tablets, (choose the one which suits you as they seem to be divided into 2 main groups, homeopathic doesn't work, chat to the pharmacy staff) use a nasal spray and eye wash like oprex daily even dull days. Try and establish what you are allergic to so you can avoid that, mine was tree pollen. Sleep with the windows shut and stay in in the early evening when the pollen is settling at the end of the day, shower at the end of the day before bed.This wasn't fool proof and never cured it, nothing does, but it was manageable. You really have my sympathy, there is nothing that makes you feel as miserable as hayfever and people who don't get it tend to just brush it aside as one of those things when it's so much more. My husband now gets it but after 30 years of giving me no sympathy I'm now getting my own back.
