I have similar allergy problems (and mine have gotten worse in my 30s) and am getting by on Allegra and an inhaler. If they get much worse, however, I'd consider shots. You might just try to the Singular/Allegra/inhaler combo and see if it works. I haven't had a sinus infection from the for a while, but I feel your pain. It's awful. My eyes--especially when I ride--have been the worse. I know of others who have tried accupuncture for a variety of problems, but it seems like a big commitment as well.
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
