Summary
This study tested whether a medication called solriamfetol, cognitive behavioral therapy for insomnia (CBT-I), or both together can help people with insomnia sleep better and feel less tired during the day. 115 adults with insomnia took part. The goal was to see if staying awake longer during the day could help consolidate sleep at night.
