"i&#039;ve tried several different sleep medications for insomnia and while attempting to get used to the cpap machine for sleep apnea. ambien cr works great, i can get a full nights sleep, however go to bed within 1 hour of taking the medication or you will feel a bit drugged. i don&#039;t recommend taking every night, it is addictive (try not to take more than 3 nights in a row). it is more difficult to wean off from than regular ambien. overall, if needed this is a good medication if taken responsibly."
