The Effects and Side-Effects of Sleeping Pills
Hangover Sleeping pills are known to reduce the amount of delta sleep obtained. This feeling of ‘not having had enough sleep’ associated with a lack of delta sleep makes the next day hangover all the more unpleasant.
Almost every sleeping medication, including over-the-counter remedies, will leave you with a level of grogginess, thick-headedness, confusion or a ‘spaced-out’ feeling. These hangovers can be severe, affecting your reactions and ability to think, making driving or operating machinery very dangerous. In my experience, there is not a single conventional sleeping pill that does not cause some degree of hangover.
Depression and Mood
Sleeping pill hangovers often seem to be associated with a very low mood. Overall, the feeling of a sleeping pill hangover can be worse than the feeling after a sleepless night. Not only is delta sleep reduced, but many prescription drugs are known to reduce the time spent in REM sleep, which means that they interfere with mental recovery and emotional well-being.
Bearing this in mind, it is not surprising that sleeping pills often cause daytime anxiety and depression. Because insomnia can cause depression, it is often thought that insomnia medication may help to treat depression, and conversely, depression is sometimes thought to be the cause of insomnia. This results in anti-depressants such as Prozac being prescribed for insomnia patients, whether or not they have actually ever claimed to be depressed.
