Pollen allergies help!

Hi! I’m a recent transplant from California (moved here last summer for my husband’s work) and have never been one to suffer from seasonal, or really any, allergies. However, this pollen got me gooood. Itchy/ burning eyes and nose, so much sinus pressure, dizziness from said sinus pressure, and overall I feel really weak and tired and haven’t had much of an appetite. How do you all handle this? Do locals still experience this kind of reaction or is it something you get used to? Have other transplants felt this and how long did it last? What medications do you take? I got sudafed for the sinus pressure and have been taking zyrtec as well but I don’t think that’s cutting it. Any help would be much appreciated because I was like a zombie at work today and I’ve read that the pollen sticks around for 2 months so I need a fix for this asap!!

update: so I went and got allegra and afrin (I’m aware of the risk and being careful) and I already feel 10x better about an hour later. if that stops helping I’ll definitely look into the other suggestions!
