So you think alcohol can help you catch some z�s? Not really, even if alcohol acts as a sedative. It does depress the central nervous system but that is also why instead feeling refreshed after waking up from a night of drinking, you get hell. Try a glass of warm milk instead. Milk contains tryptophan which is an amino acid that the body converts to melatonin and serotonin which in turn induce sleep, without a hangover the next day! What more is that milk can easily give you a burst of energy when you wake-up. If I were you, I�d trade that whiskey bottle to the real deal � milk.

One other way of fighting fatigue is by getting balanced nourishment. Iron in foods such as spinach, raisins, liver, etc., can enable easy transport of oxygen in the blood to the different tissues. One cause of fatigue is lack of oxygen in the body. B complex vitamins such as pantothenic acid, folic acid, thiamine, and vitamin B12 can be found in fortified cereals, beef, chicken, turkey, fish, egg, milk, and shellfish such as clams and crab. Deficiency in these vitamins and minerals can result to fatigue and other problems. And of course, control your food intake. An overstuffed stomach can also cause short-term fatigue.
