>>23777877I've heard some "neural" - vibral (or whatever it was called) wave stuff. And I actually got sick from it. Felt nausea. Not trying this stuff anymore.
Same happens the first time I use in-ear headphones with a boneconductor. On second use (like second day) it doesn't come up again.
When I started drinking coffee and I was drinking the "real coffee", with that I mean the real automats at offices with whole beans that get shredded/grounded on use I had times I could "feel" the caffeine in the brain. With that I mean it actually burned a little in specific areas of the head/brain. I then found a study on caffeine with brainscans and it very much matched regionwise where I've felt the burn. The receptors are there situated.
