In my EXTENSIVE experience, STAY AWAY FROM AMBIEN!!! That stuff, to me, was much more dangerous and MUCH, MUCH harder to get off of than benzos. I got off benzos (Xanax, Ativan, Klonopin) all pretty easily compared to Ambien. Opiates were much easier than Ambien too. The sleep you get with Ambien is just doped-up not very good sleep anyway, so why bother? The problematic part about Ambien is that it's SO addictive, it won't be long before you cannot sleep at all without it. Then you'll need more and more of it. It's a creepy drug and has significant withdrawal symptoms, which were, for me, at least 10X worse than benzos. In the end, when I c't'd off Ambien, I was in detox and went a total of 7 days and 6 nights without one single minute's sleep. Not one minute... not even one second. Then I got 45 minutes horrible, nightmarish sleep on the 7th night. I took months to get back up to 5+ hours sleep and then it took years to get back to 8 hours sleep.
So that's my 2 cents. I wouldn't toy with this drug, even on an occasional basis. It messes up the brain badly. I can see that more clearly than ever now that I am 95% healed, at 2-1/2 years clean.
Good luck and yeah, try melatonin or a little Benadryl to make you sleepy. Pretty much anything besides Ambien or other benzos.
