What are the symptoms of ambien (zolpidem) withdrawal and symptoms two weeks afterwards?

First, insomnia.: Second, what was the cause of the insomnia. Several medial and psychiatric problems can cause insomnia. If Ambien (zolpidem) masked a medical problem, then it would return and perhaps be more severe. While Ambien (zolpidem) does not usually have a significant effect on daytime anxiety, there is a small possibility of rebound anxiety upon its cessation. If you are having other symptoms, please see your doctor.
