When quitting drinking, it is important to be aware that there may be physical and psychological withdrawal symptoms, especially if the person has been drinking heavily or for a long period of time. These symptoms can include tremors, sweating, anxiety, insomnia, nausea, vomiting, hallucinations, and seizures. It is important to seek medical advice before quitting, as the withdrawal symptoms can be severe in some cases and medical supervision may be necessary. Additionally, it is important to have a support system in place and to consider seeking professional help, such as counseling or a support group, to help maintain sobriety.
