Having trouble sleeping on and off from the past few months. sometimes i sleep very well, sometimes not at all. psychiatrist wanted to start some meds but i said no . any supplements i can take like melatonin or vit d and doses of both?

If you have seen a psychiatrist for a behavior disorder, the treatment of that disorder will help insomnia, e.g. insomnia is a sx of major depression and antidepressant, not sleeping pill, will help insomnia. Vitamin D supplement dose not alleviate insomnia and you only take supplement if you are vitamin D deficiency. Melatonin, 3 mg, may be tried if insomnia is not caused by behavior disorder.
