Sleep Predicament

Hi guys, ok this is only going to be a short one today, there are two new reviews that I am planning on writing some time soon but at the moment I'm supposed to be revising for my As levels. Anyway, regarding the title of this post, I had absolutely no sleep last night. Ok maybe a bit but not enough. I am currently keeping myself awake with coffee (i have had only two cups which is normal so maybe it hasn't affected me as much as I had previously thought), this is because I only got to sleep at 5.30am. yes, that's right. now I've never been a good sleeper but it's getting ridiculous now. During the bulk of my exams ( I've only got 2/9 left) I found a great guy on YouTube who does this sleep hypnosis. There is music in the background and he just talks, it's amazing, I have not stayed awake to the end of a video, until last night. I don't know what was wrong with me, nothing had changed. I woke up around 8am so I've had about 3 hours sleep, and weirdly I don't feel too tired. admittedly it took me a long time to wake up but now, and during the day I've been fine!
anyway, if anyone has any suggestions just leave them in the comments and I with be eternally grateful. :)
