Yes, I get tested every year or two. I have very poor vision, with one "wandering eye" due to poor muscle control, and severe astigmatism. My right eye is legally blind, and I need strong prisms in my glasses to keep it in line, but i have no depth perception, so my eyes are closely monitored and now they do the cataract tests as well. Blurred vision is listed with the gabapentin side effects and I had it before I started the opiate therapy.

I definitely think the gabapentin causes fog, memory, and all sorts of issues, and what you are describing sounds very severe, not the typical menopause memory problems everyone talks about.

How is your sleeping? Are you sleeping poorly at night, or sleepy during the day? Narcolepsy can cause confusion between awake and asleep states.
