In addition to bringing on the blues, this cycle can result in dependence, poor nutrition. Fiber helps food go through your digestive system at a proper rate, giving a more constant energy supply. Highly processed foods merely provide a quick surge of energy which can be followed by depression. You can maintain fiber in your diet by eating an orange or grapefruit rather than just drinking the juice. Eat fresh vegetables, fresh fruits, and whole grain breads and cereals.
Some persons report receiving help by taking a concentrated vitamin B complex.
This is controversial. You can try some and decide whether or not it helps you. If it does help, then perhaps you should consult a nutritionist to see if there are other ways you can augment your diet. Changing your routines is another way to help shake the blues. Choose a different combination of clothes to wear, walk rather than drive, take a different route, eat at a different place.
