"i am bipolar and my whole life struggled with getting a good night&#039;s sleep.  ambien 10mg worked great for 2 months, then stopped working well unless i chewed the pill and took it with 0.5 klonopin.  switched to ambien cr but ambien cr gives me less sleep - i know it says its supposed to keep you asleep longer and better but regular ambien would give me 5 hours, wake up for the restroom (drink a lot of water as on lithium for bipolar) and if i take a tiny bite of a 0.5 klonopin tablet, able to go back to sleep. doctor gave me trazadone to help me sleep better as ambien 10mg doesn&#039;t knock me out like at first after a few months -- trazodone with ambien definitely knocked me out for 9 hours -- probably longer but the alarm was set."
