I have been doing once a week session for the past 7 months and this is my 8th month. I get some benefit immediately after but the session but it doesn't last long. One thing we found is training prism lenses helps me when I get dizzy and visual disturbance so I use it a lot whenever I get my symptoms. Also ordered one more custom made prism glasses.

Seems like something wrong in the vision but can't really pin point. Yes it is complex. But they try it very sincerely with one therapist for one person and they are trying their best to help me. Only some Insurances cover and most don't.

It sure worth a try in my opinion but better not expect any quick fixes.

Best.
