Insomnia
"I have severe insomnia and Ambien CR has worked very well for me. Previously, I tried the Ambien IR and while it did knock me out for a good 3-4 hours, it didn&#039;t help me to stay asleep and the Ambien CR does just that. My only complaint is some days I seem to very drowsy and sluggish, but most of the time I wake up feeling refreshed and ready tackle the day."
