I am also struggling with prisms and vision therapy. (As well as vertigo/dizziness vestibular issues).

The therapy triggers such intense headaches that sometimes flare into migraines that I often avoid it.

The prisms have made reading and using computer easier. Then I do the vision therapy, which reveals how much my brain is suppressing, and the cycle continues.

I know we are trying to rebuild our neuro-pathways associated with vision/brain, but I have not pushed the therapy because it is too intense. I am hoping over time it will get easier to do.
