Current experience: I have had the allergy for 14 days. I take Msm, Opc and vitamin C and zinc at night. In addition, I have started the program against allergies in general. In the morning, at noon, in the afternoon and occasionally also at night. Today, finally, my eyes are itch-free, I have no tickling, no runny nose, and no sneezing fits. I hope it lasts, and continues anyway.
