Summary
The purpose of this study is to test whether a dietary supplement (low-dose melatonin) commonly used to treat night owls, administered in conjunction with a behavioral sleep intervention, will help to shift the brain clock earlier and improve mood and sleep in bipolar disorder. Eligible participants will be randomized to receive melatonin plus a behavioral sleep intervention or placebo plus a behavioral sleep placebo. The hypotheses for this study include: * Melatonin plus behavioral sleep intervention (compared to placebo plus behavioral sleep placebo) will produce a greater advance of dim light melatonin onset (DLMO), between pre- and post-treatment. * Melatonin (compared to placebo) will produce a greater reduction in Patient Health Questionnaire-9 score between pre- and post-treatment.

In addition, participants will complete questionnaires (MyDataHelp app), monitor sleep, collect saliva samples, and wear the Fitbit Device.
Participants randomized to this intervention will take 1 oral placebo pill daily. They will attend 4 weekly behavioral sleep control sessions with a therapist. In addition, participants will complete questionnaires (MyDataHelp app), monitor sleep, collect saliva samples, and wear the Fitbit Device.
An active intervention that is typically paired with melatonin to maximize treatment effects.
A behavioral placebo (which does not improve sleep in delayed sleep-wake phase disorder) to control for social/interpersonal effects of behavioral sleep intervention sessions.
