Answer: As someone who has been on every sleep med known to Man for extreme insomnia, let me offer up some personal knowledge.First, forget anything over-the-counter because that is just cold medicine basically and you will only end up dizzy and tired the next morning, like a hangover. Also, forget anti-anxiety meds like Xanax, Klonopin, or Restoril for sleeping because they are benzodiazapines (BTW Xanax and Restoril are is absolutely NOT sedative hypnotic class meds like Ambien or Lunesta, they are benzos, so I think the certified pharmacy tech above me should study a bit more) and the benzos are soooo extremely addictive you may need to take them forever once you start just to stave off the very nasty withdrawal. As far as Lunesta goes, you can see what it does for you, but my experience was bad. First off, it just did not work and made me feel very depressed. Second, there is a good reason why "unpleasant taste" is mentioned first before any other side effect in the commercial. It is a very common side effect and it is awful. Upon taking the pill, you will probably start to get an absolutely vile bitter metallic taste in your mouth that will make everything you eat or drink taste disgusting (even pure sugar. I tried it!), and it may last up to 24 hours after. So certainly try Lunesta and see, if you want, but just be forewarned. Trazadone and Remeron, which are prescribed a lot for sleep because of their heavy drowsiness effect is another option if you are in dire need of sleep because they do knock you out cold, but those are anti-depressant meds so you might want to avoid it if you have no depression problems, but you could try them a just as "emergency" sleep meds now and again because they don't cause much addiction at all that I have experienced. Now, Rozerem does not actually contain any real "sleep medicine" which is why it is not addictive, however that also makes it not work very well for bad insomnia because it just increases natural melatonin production in the brain which is the chemical that makes us feel sleepy normally. Melatonin is also sold on its own as a sleep aid, along with herbs and such like Valerian Root, but these things probably would not work for you because they are not powerful enough and may also cause very negative reactions as far as mood goes because they are herbal and therefore, not FDA monitored or approved. Overall, the thing that really worked best for me was Ambien CR (controlled release) . It is not like the original Ambien because it releases two doses of meds. One time to get you to sleep, and then again to keep you asleep so it feels a bit stronger than the original, but as long as you don't overdo it with the dose there is no real addiction to worry about. So my suggestion would be to try the CR if you haven't and if you have but it has stopped working, it may just be that your body is too used to it so just stop it for a few days, if you can , so it is out of your system and your body is completely "off" it, and then start it again. It's kinda like tricking your body into thinking it is a new med again so it works. You may have to repeat this on-and-off process with the Ambien CR, but it is the only sleep aid I have come across so far that really works.
