L-Tyrosine is not tolerated by many, especially the high stressed types.

Have you tried L-Theanine? It helps the brain settle. I take L-Theanine and 5-HTP. They are a life saver. I was on an SSRI for 13 years... Yuck.

What is the goal with Olanzapine? That is a harsh psychotropic drug. I took it for 6 weeks a decade ago to stop dangerous stress induced weight loss.

I just watched a YouTube that talked about how video games can retrain the brain to a new function. Good ol'e neuroplasticity at work.

What part of the country do you live in?

If you have $10,000 to spend, CogFX in Utah or Amen Clinics might be a consideration.

If I remember, Chris learned how to settle his brain over time. He had a lot of other life issues, too.

Dr Walker's neurology clinic in Houston has done some great work with neurofeedback.
