Can't sleep

I really hate that nights when u try to sleep but u just can't. Tonight is one of those nights. After my shower i was really confortable on bed with my pijama, my laptop and a movie (I was watching " The Incredible Spider-Man" but that is not important), when after an hour of a movie I decided to stop it, close my computer amd go sleep because tomorrow morning i have to awake early. So... here i was, trying to sleep, turning arround: left-side ... no, righte...no, n...my back...mm n, on my cheast...no... and once again..h And if the fact of being an hour turning on bed, trying to seep is not enough.... while weiting this post (from my phone...) I could hear a MOSQUITO wispering on my ear. OMG they are back!! Now is deffinitive:There is no way I can sleep tonight!!!
