For Hay Fever I am relatively new to this never had allregies before. The one thing I hate is that nasal drip. Nothing worked for me. I have tried every type of spray to try to get rid of the issue I have with dripping on the back of my throat.I need to blow my nose a lot after use and that nasty bitter taste I get from all of them. I saw Omnaris commercial one day I was hesitant to try it but was at my wits end with the suffering so broke down and decided to buy it I was surprised it had no nasty taste and worked wonders It is the best so far. I will continue to purchase this product.
