Some users report hangover-like symptoms of being drowsy, having a headache, being sluggish, and being irritable after waking up if the medication is taken before sleep. This is likely the result of the medication's long half-life, which continues to affect the user after waking up. While benzodiazepines induce sleep, they tend to produce a poorer quality of sleep than natural sleep. Benzodiazepines such as clonazepam suppress REM deep sleep. After regular use rebound insomnia can occur when discontinuing clonazepam.
