I need allergy advice

I have been suffering with seasonal allergies for most of my life. When I was younger it seemed to affect me a lot. As I grew up it seemed to not bother me quite as much. I’m not sure if it’s because I was just too busy to notice, or it just got easier to handle. However, in the past few years it has seemed to pick up a lot. I need some allergy relief advice, and I need it quick. I’m not sure if i can continue using my current meds. They just don’t seem to be working like they used to.
