The lowdown. While it is possible to die from sleep deprivation, your body will eventually force you to sleep, even if you have insomnia.
Will your body eventually force you to sleep? Yes, if you haven't had enough sleep, you will fall asleep. Sleep latency (the time it takes you to fall asleep) is impacted by how much your body needs to sleep.

The short answer is: Yes, in many cases, insomnia can resolve without any help from a doctor — but it often depends on recognizing and addressing the multiple problems that can add up to a major disruption in sleep.
