Hay Fever cure

Hi
I used to get hayfever every summer i needed hayfever tablets and nasal spray symptons were bad.But i don't get it now.Every season april or may i have to change my diet to virtually all organic food and my soap and deoderant spray must have no chemicals.

I can get away with 2 evening meals with some pesticide food a week,its a vegan diet with raw vegetables eg spinach and brocoli,lettuice,tomato carrots.
i have been on it for 15 or 16 years.
Its 100% gone now.If i change my diet in hayfever season the symptoms takes 4 days to wear off .
One year i changed my diet and still had symptoms because i forgot to change my soap to none chemical.
One years i gave my former meal pesticide grapes a good wash but still had symptoms
Its worth a try and it tells me that the pesticides in my food and chemicals in my soap gave me hayfever.Hope this info helps,John
