Hi Jerricho
I also suffer from hayfever, though not every year. This year has been awful!!!
My first hint. Take whatever hayfever tablet before arising. When you first wake, the nose is not running, however as soon as you start to move, the whole hayfever reaction gets into action. So take tablet, lie there for 1/2 hour (go back to sleep if you can). That gives me the best chance of a symptom free day.
If your symptoms start at some other time (like out for a walk on a day when you'd had no problems up until then) take it asap and if you can lie down until it works (when you get home!!) then do, I think that gives a better chance of it working.
Like Spork, I also find that showering provides some relief.
Air conditioning, not too cold, is great, as it keeps the spores out to an extent.
I use Claratyne. It does not make me drowsy, and provides reasonable relief most days. Some days I also take a 2 cold and flu tablets (non drowsy) to make the symptoms go away until the Claratyne has time to work, especially if I can't lie down to stop symptoms, as the Claratyne seems to need help to stop vigorous symptoms.
This has been fascinating reading, as the varied experiences and suggestions are interesting and we can always learn new tricks.
