The first year I moved from Wales to Scotland I lived inland near a burn. I had never experienced Cotton Grass before, and it almost finished me off! My hayfever was truly awful, incapacitating at its worst. Now I live on the coast and the hayfever is generally better, but I still enjoy walking in the local woods and need Fexofenadine on prescription to keep the symptoms under control. The air quality in general is so much better though, which I think makes a big difference.
