Since lithium is more effective in controlling mania than depression, controlling mania would tend to help the patient sleep. In the predominantly depressed patient it may interfere with good sleeping. I think your prescribing physician or psychiatrist can advise you best, however.

It would be best to discuss this with your Psychiatrist. If you are not confident with your Doctor see another for a second opinion. It's good to have a physical exam to rule out illness. Sleep is very important for physical and mental health. You may need a sleep study to determine why you can't sleep. Also consult with a Clinical Psychologist with expertise in multiple types of psychotherapy.
