keg,

It would be great if you could elaborate about your experience with HBOT.

How many sessions? How often?

What improvements did you notice?

How far into your recovery did you start the HBOT?

How much did you have to pay?

Your qEEG neurofeedback sessions were likely too long. Shorter sessions more frequently might have been better. Exercising the brain to fatigue would be counter productive. Most neurofeedback is designed for ADD/ADHD where the longer sessions are not a cause of fatigue.

Was it the kind of neurofeedback where you tried to modify the wave forms as a sort of video game?
