Description
When you stop drinking, you may experience cravings for alcohol. Alcohol abuse affects your brain's neurotransmitters, or chemical messengers over time. These changes might result in tolerance, or the need to drink more to achieve the same effects. Craving is associated with memory . Alcohol and other substances flood our brains with dopamine and other reward substances. Our brains and memory still associate drinking with this rush of reward long after we've stopped drinking.
