Feeling tired or moody all the time can be due to a host of causes. And they can be hard to pinpoint. Too much stress, too little sleep, a lack of exercise, or the foods you eat may all play a role. So can some of the beverages you drink, including alcohol. As an experiment, try not to drink any alcoholic beverages for a few days. Then see if you notice any improvement in your sleep, energy, or mood. You may be pleasantly surprised.
If you feel you drink too much or have trouble saying no to alcohol, talk with your doctor. He or she can help you come up with a plan to gain control of your drinking.
