Could you talk to your doctor about maybe a different sleep medication, doesn't seem like the ambien does you any good. Other then that there is valarian, but I don't know if you are on other meds or if it would interfere but its a very sedating herb that can certainly help you sleep...I have a tincture of that(it comes as tea, herbal supplement capsules or one can even just buy a bag of valarian root and make tea or tinctures out of it themselves) I also am prescribed trazodone, but if I take the trazodone I wake up pretty drowsy and not as coherent as I'd like to be. I do not take the valarian and trazodone together though its either one or the other.

I have a friend who told me he was taking ambien for sleep at one point and he ended up giving people rides home and driving on it and then could hardly remember the next day..that could have been very dangerous so he stopped taking it. Ive heard other undesired experiences to..I know i would not want to try it.
