Has anyone had problems with their eyes, as in over production of tears/possible blockage? I've had this for a couple of months and although reassuringly, my eyes are healthy and sight not too bad, it is really irritating. My doc has more or less said there is nothing he can do and my optometrist says that there is only a 25% success rate in clearing blockages and it isn't a particularly nice procedure! Any ideas would be good
