JayRecovery and Relapse.Despite some improvement after withdrawal subsides, sleep patterns may never return to normal in those with alcoholism, even after years of abstinence (3,21). Abstinent alcoholics tend to sleep poorly, with decreased amounts of SWS and increased nighttime wakefulness that could make sleep less restorative and contribute to daytime fatigue (22). Resumption of heavy drinking leads to increased SWS and decreased wakefulness. This apparent improvement in sleep continuity may promote relapse by contributing to the mistaken impression that alcohol consumption improves sleep (23-25). Nevertheless, as drinking continues, sleep patterns again become disrupted (3).
