I never really sleep for longer than 2 or 3 hours. I'm up too late, too often and too much > < So "waking up" for me is whenever I have to actually get out of bed and start getting ready to leave. When I didn't have to work it was great cause I wouldn't hesitate to just stay up til whenever and sleep if I could, when I could. Now though, it hurts when I don't get at least 5 hours. Trying not to drink and take pharmaceuticals, but the natural shit just doesn't cut it. I guess I close my eyes and pretend I'm asleep sometimes before I have to get up.
Wait, what was the question?
Assuming you're not just being a trollface...
My boyfriend has a similar sleeping condition; if I catch him napping during the day or sleeping late, I never rouse him; it makes up for all the nights he hardly sleeps at all (he's also weirdly happy when he comes home from work dead on his feat; it means he can sleep later). All nighters aren't a feat most of the time, they're just what happens. Been this way since he was a kid, so no it's not just twenty-something weird sleep habits.
Anyway, suggestions! You mentioned all-natural stuff so you're probably on it already, but try using Melatonin to get drowsy, cutting off caffeine and sugars will help, too. Also set yourself a bedtime, even if you're not sleepy, lying in a bed instead of sitting upright will help get you there; try changing the lighting after dinner, not enough to strain your eyes but instead of keeping the ceiling lights on, maybe invest in a couple table lamps. If you don't want to lie staring at the ceiling until sleep comes (and who does?) you can use your laptop or phone or handheld game system or even (HEAVENS TO BETSY OLD FASHIONED) a book. This doesn't work for everybody, but soothing music or even the TV as a dull background sound can help, too (I like to have a fan going to help me sleep, and I don't have any kind of sleeping disorder.)
EDIT: I'm not trying to be an expert, or a know-it-all, I only know what I've seen from living with someone who has a similar problem, if you've talked to medical people about it they probably know more than me, but the internet is a public forum, and the whole point of a forum is for people to swap ideas and learn new things from outside sources.
