There's nothing fun about allergies, what with the congestion and other symptoms basically ruining any fun you're trying to have. It's one of those things that's tough to take care of without meds that can leave you drowsy or cracked out, which is why it's understandable that people are willing to try unconventional methods to get rid of their stuffy noses.
The SneezerBeam is a tiny device you stick up your nose, where it shoots beams of light up into your sinuses. Apparently, it works "by using two combined beams of light to inhibit the cells in your nose that release histamine, which is at the center of what triggers your allergic symptoms." It sure sounds like BS to me, but hey, maybe it isn't. Worth a try?
