Yer it has, I had a very busy winter break so my sleeping patterns wernt regular at all cos i was staying up late alot. As for stress im in my final year of my A-levels so my exams are coming up this year. Now im back at school my sleep patterns are regular but probably not best they could be. I havent had another episode yet.
Thankyou for your advicce :)
Get better sleep habits(as you said) and try to become stress free. Is your life changing a lot in some way? New job or people? Try to relax. I had it before.
I don't know how to prevent it, sorry. It occurs where your body is in the phase of being paralyzed during sleep and you wake up prematurely which you're not supposed to. I would say it sounds like you have a case of insomnia for some reason if you started having trouble falling asleep after having trouble staying asleep.
