”Get to bed as early as possible. Your  body (particularly your adrenal system) does a majority of its recharging between the hours of 11 p.m. and 1 a.m. In addition, your gallbladder  dumps toxins during this same period. If you are awake, the toxins back up into  your liver, which can further disrupt your health. Prior to the widespread use  of electricity, people would go to bed shortly after sundown, as most animals  do, and which nature intended for humans as well.” (drmercola.com).
