After Effects of Alcohol on Moods:

Alcohol depletes the brain of serotonin levels, causing depression.
Alcohol depresses the central nervous system, sometimes uncapping underlying anger.

Alcohol is a celebratory drink and in some cases can even be beneficial to your health. However, if not used in moderation, it can have negative psychological and emotional effects. Drinking alcohol can increase the intensity of an emotion you are already experiencing, says Dr. Bill Boggan of the Chem Cases website. After you stop drinking, chemicals in the brain can also cause other effects on mood.

Anxiety
Drinking a glass of wine before bed is often suggested to those who are too anxious to sleep. In fact, alcohol is a depressant and will give you a relaxed feeling. However, if you often use alcohol to deter your anxiety, you are actually creating an unhealthy cycle, as drinking alcohol causes lactate to increase in the blood, creating intense anxious feelings after the drinking has ended. Because of this, you easily turn back to another glass of alcohol, furthering the alcohol trap.

Depression
When a person realizes they have been caught in the cycle of alcohol addiction, it can cause a feeling of hopelessness and despair, which eventually turns into a depressed condition. According to AddictionInfo.org, alcohol reduces the amount of an important brain chemical, serotonin, which is a mood elevator. When serotonin levels are depleted, this results in depression.

Anger or Aggression
Alcohol often unmasks hidden emotions. If the after-effects of a long night of drinking don't cause anxiety or depression and there is an underlying current of anger, it may become exaggerated and turn into aggression. Alcohol depresses the central nervous cystem, which can cause moods and emotions to become unhinged. If the effect of anxiety goes unsatisfied, with some personality types, it may turn into anger.
