I suggest you enjoy your placebo effects and take a physiology course. (You can verify that this is the placebo effect by studying and doing research, but I won’t link how to do that for you, I know that’s unkind of me to do)
Go peddle your snake oil elsewhere.
OP, go see a medical doctor who knows more about human physiology than some snake oil sells person on the internet.
Are there tutorials on how to do this? Should it be set up on a server on my local network??? How hard is it to set up? I have so many questions.
