The memory loss is the drug imo. I've taken Ambien for maybe 7 years off and on. I was told that with my doctor's approval for long term use , it was okay.

If my anxiety is bad at night, and I've had a few days/nights without good sleep, then I will take 10mg of it. But mostly l don't need it lately. The reason i try to stay off of it is the memory loss and the total lack of motivation in the morning or entire day after I use it for a few nights.
