I took ambien when it was first approved and I was living in the states. I think you will find memory loss to be less of an issue with zopiclone. Let me know how things turn out.

If I'm not mistaken there is a class action suit against the makers of ambien in the states because of all the bizarre and dangerous things people would do while under the influence then never remember.

While I was on the stuff one night I decided to leave my bed and sleep on the back porch. I have no memory of it though.

Also w/ zopiclone don't feel too tempted to take more than the recommend does, it is absolutely useless as a recreational drug unless your idea of fun is having really foggy memories. What I'm saying is that past 10-15 mg of the stuff you won't really notice much difference aside from wasting your pills.
