When nerve interference is removed, nerves work better. That means they do what they're meant to. If you should feel pain, if you should feel sick, if you should feel fine, your nerves will carry that message. An adjustment makes your nerve system work better so you can experience your world correctly. Then you can take right actions based on right information. I.e. If you are putting garbage in your stomach and the nerve interference to your stomach is removed, then you will likely feel sick (you might even throw up). That is a good thing. That's your inborn intelligence looking after you.
