I have taken Ambien for about 5 years as a sleep aid. I am very much the insomniac. This has been for most of my life, as well as, I sleepwalk taking time to cook (only the microwave), although I put my stock pot on the burners of the gas stove, put all my med bottles in it and went on to something else. I awoke in the morning to find the meds all in the pot. The Ambien is very good, it will help me sleep for 6-8 hours undisturbed. Waking, there is no groggy feeling, I feel actually very refreshed. The only problem I saw was I did not dream that I could remember. I enjoy analyzing my dreams. Took courses in it and have learned a lot. But every now and again I stop taking the Ambien to see if I sleep without it. I have never slept at night for more than 2-3 hours with help. I just get tired of depending on that help all the time. It is very nice to sleep like that again. TTFN Gina
