My hayfever is still bothering me - as the weeds, moulds etc. are all going mad outside in this warm weather. Still, I bought a new pillow (and dust mite proof case) and noticed, the next morning, that my congestion/sniffles had disappeared entirely. I could breathe perfectly through my nose - bliss! My friend kept complaining about her eyes stinging and was using eyedrops all the time. She ran out of her usual wrinkle cream - and it stopped instantly - so, it seems, the irritation was due to it getting into her eyes!
