{{Main|Alcohol use and sleep}}

Alcohol is often used as a form of self-treatment for insomnia to induce sleep. However, alcohol use to induce sleep can be a cause of insomnia. [[Long-term use of alcohol]] is associated with a decrease in [[NREM]] stage 3 and 4 sleep as well as suppression of [[REM sleep]] and REM sleep fragmentation. Frequent moving between sleep stages occurs with awakenings due to headaches, [[polyuria|the need to urinate]], [[dehydration]], and [[diaphoresis|excessive sweating]]. [[Glutamine]] rebound also plays a role when someone is drinking; alcohol inhibits glutamine, one of the body's natural stimulants. When the person stops drinking, the body tries to make up for lost time by producing more glutamine than it needs.

The increase in glutamine levels stimulates the brain while the drinker is trying to sleep, keeping them from reaching the deepest levels of sleep.<ref>{{cite web | vauthors = Perry L | date = 12 October 2004 | url = http://health.howstuffworks.com/hangover5.htm | work = HowStuffWorks | title = How Hangovers Work | archive-url = https://web.archive.org/web/20100315050850/http://health.howstuffworks.com/hangover5.htm | archive-date = 15 March 2010 | access-date = 20 November 2011 }}</ref> Stopping chronic alcohol use can also lead to severe insomnia with vivid dreams. During withdrawal, REM sleep is typically exaggerated as part of a [[rebound effect]].<ref name="sleep_medicine_a04">{{Cite book | vauthors = Lee-chiong T |title=Sleep Medicine: Essentials and Review |date=24 April 2008 |publisher=Oxford University Press|url=https://books.google.com/books?id=s1F_DEbRNMcC&pg=PT105 |isbn=978-0-19-530659-0 |page=105 }}</ref>
