Hay fever season approaches. I was reading on the internet that a lack of vitamin D can cause Hayfever to be worse so I've bought some vitamin D tablets and I'm going to give them a go. I will do anything to try and alleviate it. I've tried local honey, various anti histamine tablets, Vaseline up my nostrils, etc Has anyone come across anything that works? It's my eyes that suffer most, they itch, swell up and then get infected. It's like having a heavy cold for 3 months and by June I am worn out with it.
