Summary

This trial is testing whether a dietary supplement called low-dose melatonin, along with a sleep improvement program, can help people with bipolar disorder sleep better and improve their mood. Participants will be randomly assigned

Who is the study for?
This trial is for individuals with Bipolar Disorder who also have trouble sleeping at the right times, like night owls. Participants should be interested in trying a dietary supplement and behavioral sleep techniques to improve their mood and sleep patterns.
What is being tested?
The study is testing if taking low-dose melatonin along with learning new sleep behaviors can help people with Bipolar Disorder fall asleep earlier and feel better. Half will get real melatonin; the other half gets a fake pill (placebo), both with behavior training.
What are the potential side effects?
Melatonin may cause drowsiness, headache, dizziness or nausea. The behavioral intervention typically doesn't have side effects but could include temporary stress from changing habits.
