When alcohol is discontinued, however, these alterations persist, at least for a while, resulting in increased arousal that manifests as withdrawal symptoms, including sleep disruption.

Before we look at the effects of alcohol on sleep in detail, here’s the basic bottom line. The more you drink, and the closer your drinking is to bedtime, the more it will negatively impact your sleep.

Schiavi and colleagues reported no significant differences in REM sleep time and REM sleep latency when comparing 20 alcoholic men with 2 to 36 months of sobriety with control subjects. The acute withdrawal phase after cessation of alcohol consumption lasts approximately 1 to 2 weeks. This section discusses persisting sleep disturbances during both recent (i.e., lasting 2 to 8 weeks) and sustained abstinence.
