If it started in the fall, it could likely already be chronic. Cognitive behavior therapy for insomnia is the only evidenced-based non-medication treatment for insomnia, and has equal efficacy to hypnotics within a few weeks, and higher efficacy afterward. It is typically an 8-week program that requires sleep restriction, so patients are often VERY sleep deprived for 2-3 weeks, then they really start sleeping. It is recommended to use a trained sleep physician or therapist, but if there is no one nearby, you can try following instructions online. You can read more about it at
