How can one overcome chronic insomnia?

Chronic insomnia can be challenging because the body may adapt to this unhealthy state, making recovery difficult. To address it, one must first identify the underlying causes of insomnia and tackle them systematically. There may be multiple reasons contributing to the problem, and it's essential to eliminate them one by one. If one cause is addressed and another is not, the individual may mistakenly believe that the first cause was ineffective, when in fact, multiple factors may need to be resolved.
