Alcoholics may lie about their drinking for a number of reasons, including:

Denial: Alcoholics may be in denial about the extent of their drinking, and lying about it may be a way to avoid facing the reality of the problem.

Shame and guilt: Alcoholics may feel ashamed or guilty about their drinking, and lying about it may be a way to avoid these feelings.

Fear of judgment: Alcoholics may fear being judged or criticized for their drinking, and lying about it may be a way to avoid negative reactions from others.

Covering up behavior: Alcoholics may lie about their drinking to cover up other behaviors, such as spending money on alcohol or engaging in risky behaviors while under the influence.

Maintaining relationships: Alcoholics may lie about their drinking to maintain relationships with friends, family, or coworkers who disapprove of their drinking.

Addiction: In some cases, alcoholics may feel like they cannot control their drinking, and lying about it may be a way to continue using alcohol despite negative consequences.

It’s important for alcoholics to receive appropriate medical and therapeutic support to help address these issues and restore their mental and emotional health. It’s also important to address the underlying issues contributing to the alcoholism, such as denial or addiction, as part of the recovery process. Therapy or counseling can also be helpful for addressing lying behavior and learning to build trust in relationships.
