If you blow a fuse in your house, you can't expect to get power back by lighting a few candles and searching for food with flashlights. You've got to find the bad one, replace it with a good one, reset the system and power up. Same goes here.
To restore your energy—both at the "feeling great" level and at the chemical level—it just takes some awareness and action to get your body headed in the right direction.
As a reminder, always consult your doctor for medical advice and treatment before starting any program.
