My experience, is that melatonin is a realy fucked up drug
it will strip your psyche and feed it back to you in one epic motherfucker of a dream
but then seems to loose that quickly and not realy do anything at all, and is totaly pointless.
Plus the harder I work physicaly, the better I sleep, eat, think, plan, strategise, and reafirm my capacity to deal with stuff.
For people who dont do physical work, like my father, leading a very,very, disaplined orderly life, with lots of self care,and even when when things go wrong maintaining routine and habits, seems to be key.
