Does Chamomile tea really help with insomnia?

When do you have it ? Hot or cold?

I take melatonin 3 mg but it doesn't keep me asleep for long. Sometimes l would take Hydroxizine if struggling too much ... M also looking for valerian root tea online. But didn't yet find one . its the racing mind at night .l am on prozac 20mg as well. I am looking to some alternative to melatonin .
