Yes, alcoholics can experience mood swings. Chronic and excessive alcohol consumption can lead to changes in brain chemistry, including the neurotransmitters that regulate mood. This can lead to symptoms such as irritability, anxiety, depression, and even aggression. Furthermore, the impact of alcoholism on an individual’s relationships, work, and other areas of life can also contribute to mood swings and emotional instability. Treatment for alcoholism can help address these issues and support the individual in achieving greater emotional stability and overall well-being.
