Curlycrly,
I can't say that I have but then again I don't really suffer with allergies except hayfever when the weather is extremely hot and pollution and pollen is high.
However, if you have allergies eg Hayfever etc I think you should try taking Bee pollen as this helps to build up your immune system and protect from hayfever and such allergies about 2 months before the hayfever season.
