I like ambien because it helps me fall asleep fairly fast. If I don't take it right before bed, it makes me weird. One night I was trying to type an answer to a question and it looked like the circles in the background of this section were floating. As far as Lunesta goes, I don't care for it. I wake up and have an awful taste in my mouth like i fell asleep with a chewed up aspirin my mouth or something. A lot of people have that problem.
I took ambien and it was great. I actually slept. Never tried Lunista so I can't comment on that one. Either way just becareful. Any drug rather marketed as being non habit forming can be if used in the long term.
