insomnia
"My experience with ambien was not very good. Ambien is a pretty terrible sleep aid and I'm sure you'd be better with little sleep and tired, Than waking up feeling like crap all day and tired. It makes me feel pretty rubbish all day and it only last like 4 hours, So I'll wake up 3 or 4 hours later super tired and can't go back to sleep. Your body Builds tolerance to this drug very fast, After the 4th or 5th time of using it,  it's effects are very very minimal. Also if you suffer from acid reflex, this drug will make it 10 times worse. If your desperate for sleep, This drug  will make you sleep, but with great consequences."
