insomnia
"I suffer from both sleep onset and sleep maintenance insomnia. My doctor recommended that I take 5 mg (half a dose) of Ambien prior to bedtime. In terms of overriding sleep onset insomnia, this product is excellent. It also does a good job of keeping me asleep throughout the night; however, I still wake up approximately five to six hours later. (My ideal amount of sleep is seven to eight hours). Still, getting six hours of uninterrupted sleep is preferable to eight hours of fitful sleeping. It's also worth mentioning that Ambien doesn't leave me feeling groggy in the morning.

Unlike some of the other reviewers here I haven't experienced any of the more pernicious negative side-effects, e.g. the various somnambulist activities."
