Abstract: This document provides methods and materials related to managing weight, supporting appetite control, and controlling cravings associated with smoking reduction or cessation regimens and/or nicotine reduction or cessation regimens. For example, compositions comprising an agent to support acetylcholine and an agent to support one or more biogenic amines, and methods for using such compositions for craving and appetite control are provided. Methods and materials to reduce cravings associated with the reduction or cessation of the use of chemical substances (e.g., drugs of abuse, including opioids, cocaine, methamphetamine, cannabis, alcohol), and to reduce cravings associated with addictive and/or compulsive behaviors (e.g., gambling, sex, and repetitive behaviors) are also provided.
