"ambien has been hit or miss for me. when it works it&#039;s bliss! 2 out of 3 days it doesn&#039;t work well. the cr is supposed to help me stay asleep but at best i get 4-6 hours of sleep. it&#039;s not the greatest sleep - i fall off and wake up frequently without feeling i&#039;ve slept, but it&#039;s better than staring at the ceiling till dawn. it&#039;s expensive!"
