I discontinued the alcaftadine eye drops yesterday to see what happens and my eyes are a bit better (!) but there are too many variables to draw a conclusion.
step-up to 3x dosing of fexofenadine would have only reached steady state today. and, there was some rain over the weekend, so pollen is likely down.
I'm wondering if I developed a sensitivity to the preservative... well, seeing as the olopatadine eye drops I ordered to compare have 3x the concentration, I'll soon find out.
