Are you weaning yourself off sleeping medication, only to find your insomnia is worse than ever? You may be experiencing rebound insomnia. It is the withdrawal side effect when some prescription sleep aids, particularly in the benzodiazepine family, are stopped.
Some sleep experts say that rebound insomnia is the body’s way of readjusting to sleep without medication. It generally lasts from a few days to as long as three weeks, but eventually it disappears. The problem is that people who have it frequently turn back to their sleeping medication, since they are so miserable with their lack of sleep.
Benzodiazepines can cause rebound insomnia because they may keep the body from sleeping appropriately, in a restorative cycle. A healthy, restorative sleep cycle is when the body alternates between REM sleep and deep sleep. Benzodiazepines can suppress the REM cycle, causing less restorative sleep. However, benzodiazepines are the most commonly prescribed class of sleep medication. They can also have other side effects, especially in the elderly, including memory loss, dizziness, nausea and incontinence. These drugs can also cause depression, or may exacerbate an existing depressive condition.
Some newer drugs are less likely to cause rebound insomnia. These include zolpidem, zaleplon, eszopiclone and ramelteon. These drugs act on a different part of the brain and their side effects are usually not as pronounced, and they are mostly safer for the elderly.
A good way to treat rebound insomnia is to simply allow it to happen, without worrying about it. This is usually easier said than done, but someone who can simply live with the sleeplessness for a few nights may find himself or herself sleeping much better afterwards. Remember that this is a normal side effect, not an indication of ill health. Good sleep hygiene practices are also important. These include: using the bedroom only for sleeping (not as an office); developing relaxing sleep rituals, such as reading or listening to soft music; not exercising right before bedtime; arising and going to bed at about the same time every day; and not consuming caffeine or nicotine within six hours of going to bed.
