In the spring time my allergies are horrible. I am allergic to anything you can think of grass, trees, dust, the list goes on. I think I have tried just about anything under the sun. I have tried the Afrin nasal spray to help with my congestion before and here are my quick thoughts. First, it is easy to use. I was a little weirded out by putting it in my nostril, but you just put it in your nostril and spray it while inhaling. Super quick and easy, but it feels really weird. I felt like initially it worked by relieving my congestion and runny nose. But as the day went on, my symptoms returned and there was nothing else I could do, you can't use this product again for another ten- twelve hours. For me to not take anything else for that long, I expect my product to work all day long, and this nasal spray just did not meet those expectations. It didn't cause any side effects that were harmful, and it worked the first half do the day. But like I said, I wanted it to work at least twelve hours and it didn't.
