What are your experiences from taking ambien?

I have been prescribed it but have not taken any yet. I will be taking 10 mg once a night. My doctor wants me to take it every night because I am having a horrible time sleeping. I have read up on some of the stories about amnesia and specifics of what they do during sleep. what is the likely hood that I will sleep walk/drive/eat/talk/make phone calls, etc? I want to know more before I take it tonight. Thanks!
