All sleeping aids run the risk of at least psychological dependency, so whatever you try keep that in mind.
I have an Ambien prescription and have never had any of the weird side effects, though a friend of mine has done the sleepwalking/grazing thing once or twice. It appears to effect different people differently. When I take an Ambien I wake up feeling less dopey than I do when I take Tylenol PM, which is another option.
I tried a homeopathic remedy for a while, and while it certainly helped me sleep it also appeared to make me ridiculously horny and disabled what few filters my brain uses when in that state.

No lie. I can't explain it, but it was noticeable.
Of course there's always kind weed if you can get it.
