Sleep is really important. Just have a look at some of the research on the links between stress and lack of sleep and weight gain/overweight. Even more importantly, In the last 2 years neuroscientists just found the glymphatic system in the brain. Apparently, it takes out waste from the brain– but only if you sleep well. Sleep medications, including melatonin don’t help you achieve the deep sleep that you need to activate the glymphatic system.
For those who like information one of the main researchers is Jeffrey J. Iliff and he has a link to his TED talk on his research page.
