Examples of stimulants include:
Depressants slow you down by reducing your heart rate and pressure. Depressants may help you feel more relaxed. In some cases, they can sedate you.18

There is a link between a higher amount of alcohol consumption and the level of depression symptoms. The more a person drinks, the more likely that person is to develop major depression.
Alcohol abuse can produce or worsen depression symptoms by affecting levels of neurotransmitters in the brain. It also reduces the amount of tryptophan in the body, an amino acid that helps produce serotonin, a mood-regulating hormone.
If you have an alcohol use disorder and a mental health problem, you must seek help for both conditions.
Treatment options for alcohol use disorder (alcohol addiction/alcoholism) include:
Inpatient treatment is a program in which people receive 24-hour structured and intensive care in a dedicated treatment facility. Inpatient treatment is also called residential treatment.
Outpatient treatments are part-time, non-residential addiction treatment programs. This type of treatment is less disruptive to a person’s life. During treatment, the person lives at home and can attend school or work.
Medical detox is otherwise known as medically supervised withdrawal or ‘detoxification.' Detox is when a person is weaned off a substance while under medical supervision in a hospital.
Healthcare providers manage withdrawal symptoms with medications along with:

These therapies can help patients recognize the impact of their alcohol use. It can also help them learn how to change their behavior to control their alcohol use disorder.
The most common behavioral therapies that have been productive in treating alcohol use disorder in the United States include:
