Many of my friends and I have this problem as well. One has resorted to sleeping pills, which I don't recommend although it seems to have done the job.
The rest of us resort to all-nighters, though I will try not to do one again. One problem is that an all-nighter takes some determination to get through those early hours of the day, especially in winter when it's still dark, you'll be knackered by 8 am; if you nod off then you'll be in an even worse position.
If you succeed, you'll most probably be off the ball for the rest of the day and you'd have built up your sleep deficit. If your sleeping aim is to make a habit off being asleep by 11pm and up by 7am, then sleeping at 11pm on this first night will pretty much take you back to square one as you'll wake up past 9am minimum. I would recommend sleeping around 5pm, 6 latest on the first night IF you take this route. It doesn't matter if you wake up a bit early the next day as you would still have sleep debt leftover which would need to be accounted for during the following night(s).
However, it just doesn't work sometimes in that, at 6pm you might get a bit of energy for somewhere(your body thinks you don't want to sleep so it wakes you up), so you might not be able to sleep till late again, so wake up at 4-5pm the next day which is useless.
Also this is only a short term solution as it probably didn't fix the cause, I have had to do too many of these only to back to the same position within a fortnight.
My recommendation is to just try and wake up earlier(get someone to throw water on you, nobody can sleep on a wet bed. book your unmissable seminars nice and early which will make you think twice about hitting the snooze button. Then just get to bed earlier(again around 6pm for the first night, judge it yourself, but don't care about when you feel tired just be in your bed with phone on bedside not in your hands + wifi off).Somebody else mentioned sleep hygiene, basically phones and laptops are big contributors to poor sleep. Also caffeine and sugar late in the day don't help.
Lastly the two I'm still not 100% about and depend more on the person are bedtime baths and exercise. Personally I would avoid the two near bed time but the other poster did actually recommend so...
Try again these next few days and see what happens, if all else fails, there can't be any harm in speaking to a professional about it.
One more thing, if you're a student I used to leave work till last minute and have to do it during the night(less distractions = in my zone). The opportunity cost of this is of course my sleep, so try your best to do your work during another part of the day, there must be an hour or two where you can work peacefully.
Remembering a few other theories which I think I'll throw out there. Don't go to bed hungry, though as I said before don't eat too late especially sugar. When you get to know yourself, you might realise that a glass of warm milk around 10 pm is best to get to bed on time.
The other theory is drink water so you want to get up early to go to the loo...though there is one about setting the heating to high so you want to get out of bed(though you may not want to leave the house then lol
); it's also supposed to dehydrate you but how that links in to the water thing I'm not sure...
Good luck man:cool
