m aware that Ambien is only recommended for 7-10 days, and
the clinical trials were
in numbers of weeks, not years. Not much is really known about
the long term effects, and it needs to be scrutinized. Unfortunately, I think it can be difficult to remove factors that contribute to cognitive impairment that exist alongside Ambien use, such as depression, anxiety, caffeine use, diet, lack of exercise, and sleep deprivation itself.
