For Insomnia "I am a hard-working healthcare nightshift worker, mother with 2 young kids. I have had to flip-flop between days and nights for 8 years now to work and take care of kids. I have taken traditional Ambien 10 mg for a long time. I need something that works fast but wears off fast because my time window to sleep is not that long. Well, I tried Ambien CR last night and will not be trying again. I thought it worked the same, just helped me stay asleep maybe a little longer, nope! It hits you little by little, just enough to make you a tad loopy but not enough to totally knock you out, and that effect lasts longer. It is dangerous because I had to even mix my regular one to even be able to fall asleep. I know my limits with the regular Ambien. Be very careful with Ambien CR."

For Insomnia "I have taken Ambien (10 mg) on several occasions for short periods of time, and it worked just fine (knocked me out in 20 min and gave me 5 to 6 hours of sleep). But, my doctor recently added Ambien CR to my nightly cocktail, and it has not worked like the doctor or the website said it would. I have been taking it for a week. I expected it to knock me out and keep me asleep. I have done everything like I have been told to do and have been taking it before bed, and all it has been doing is taking 3 to 4 hours to knock me out and makes me totally loopy in the morning. The effect is basically lengthened and delayed. I am hoping to switch back to the original Ambien formula when I see the doctor next month!"

"I came here to post my experience over the years with Ambien and Ambien CR. They were bad for me. I had issues with memory, especially with my family having to remind me of what I said and did, even the morning after, really groggy, cloudy, fuzzy. Not good for raising kids. I was helped by sweetlemon on this website in her post here: I asked my doctor about Silenor, and she gave me 3 milligram tablets. She had no samples, but I figured I had already spent a fortune on Ambien, so why not. Got 7 hours of sleep without a problem. I haven't felt this good in a very, very long time. Thank you all on this website. I can sleep now!"
