Glad you're doing better, David. Great news!!!
The way I've started to see this is as positive results from a "virtuous cycle." Like Cece says, good builds on good. You have more energy and sleep better, thanks to better cerebral perfusion. This affects mood, relieves depression, and you can think about being proactive. So, you eat better, maybe start exercising, become more social. All of this helps you physically and mentally. Your blood vessels work better, due to shear stress, better diet, and healing can happen.
Of course, this is just a theory---but it seems to be happening to Jeff....he just keeps getting better.
keep us posted, David---all best,
