You described everything I would say too. LASIK and allergy shots FTW.
I first did cluster immunotherapy in 2009-2010 with 3 initial large doses and weekly injections, it held for about 7 years. However after that I lived in 2 other states with different allergens which I think stirred things up and maybe "reset" things. When I moved back to TX in 2018, that fall was miserable and it was the first time I needed allergy pills since 2010. I restarted immunotherapy and this time went for the monthly ones since I didn't have time for weeklies. Just got the ok to stop (5 years total). Haven't needed a pill again since 2019 other than on shot days. If your allergies make you miserable, run to your nearest allergist!
For those in Plano/Frisco, I recommend Dr Milan Sljivich at Allergy Partners.
