Normally I have completely debilitating allergies from the end of August till the beginning of November. Sneezing constantly, itchy eyes -- it's terrible. This year I started the nettle and quercitin in early August and I have had NO SYMPTOMS at all, hardly even a sniffle! The only side effect I've noticed is that my nose feels a little dry on waking, but nothing like the dryness I'd experience from OTC anti-histamines like Claritin. It's amazing as I've been battling fall allergies my entire life, and now I can finally enjoy the season. So happy!
