I completed vision therapy for 5 months once a week and I felt better immediately after but doesn't last long. Now I have some prism training lenses (besides the session) which I use it whenever I get dizziness/headaches etc., and it helps a little.

Also I am wearing contact lenses which also helps. All this I found in the past 1 month. Finding the right prism lenses is what Dr. Debby Feinberg expert at. You can do some of the training at home itself. I need some serious brain training and/or prism lenses I think.
