Then what do you do when you don't fall asleep within the preferred frame of sleep? Do you just get up without sleeping after forcing yourself to like awake in bed for eight hours, hoping you can go safely through the next day with no sleep? And what if you still don't fall asleep when you should the next night?

And mind you, melatonin like everything else has risks. I'm totally forbidden taking it since it can actually kill me by putting my immune system in overdrive. So it's really important running things like these with a real doctor and not just treat yourself.
