Hi, Zolfresh (Zolpidem) is used as a sedative. However, it is advised that it should be used only for short duration. Long term intake can lead to dependence. However, in your case, I won t say that you have become addicted as of now. Your not falling asleep might be because of the fact that your depression/ anxiety is still persisting. Also, many people develop a psychological dependence that they can t sleep with out the sleeping pill. I would suggest that you should discuss regarding this with your psychiatrist. If needed you anti-depressant medications might need a review. Its better to stop sedatives as early as possible so as to prevent any chance of dependence. Zolpidem has to be tapered when you are trying to stop it. Hope this information was useful. Best wishes.
