"i&#039;ve been taking melatonin for a few months now, for delayed sleep phase syndrome and it has helped with sleep dramatically about half of the time. the rest of the time, i still usually get to sleep at my &quot;normal&quot; time around 2:30-3:30am. the problem with this is it&#039;s unreliable. you never know when it&#039;ll work and when it won&#039;t. and there are times when it just doesn&#039;t. i will keep taking it though."
