Zolpidem
"I'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'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."
