The prisms really are working great. This morning when I was in to her, to distract her from the hallucinations, I had turned on the TV, and she happily critiqued one of the presenters!I think it's still early days yet for the quetiapine. Isn't it up to 6 weeks for it to kick in fully? Bringing in another sample is a good idea.
About the prisms, it does sound like they work. I had prisms in my glasses for years, as I developed a lazy eye. I've since had surgery so no longer need the prisms.
