I had that glazed look at lots of times myself. Memory terrible and now that I'm older allergies, digestive problems and liver conjestion.
Very anxious at times, jittery, and angry at people for no reason. On a full moon sleeplessness and even on a new moon.
I think the parasites no that they make you over look that this is a problem kinda like control of the mind.
I hope they will see the light, maybe you could get a good parasite herb and give them a couple then they will notice how they feel much better.
God Bless. Chipper
