Thanks for the detailed and thoughtful response. I hope the exercises they've given you help you.

How long did it take you to get into the clinic?

Also can you expand on your horizontal nystagmus and any changes you've subjectively noticed?

Additionally, can you expand on your vertigo, the causes (is it positional?) And any affects the clinic's therapies may or already have had on you?

Lastly, have your tolerance/endurance levels improved since you left the clinic?
