I am feeling restless at night and can't sleep without zolpidem. What can I try to help me sleep without it?

Benadryl (diphenhydramine) can help. Try using Benadryl (diphenhydramine) at night. One tablet 20 to 30 minutes before sleep can produce mild sedation that last for 4 to 6 hours. This can help with sleep. In addition, make sure you are trying to change your sleep habits.
