Sleeping Disorders?

hey guys.. its been quite some time u hvn't heard from me. nothing much has been happening lately because everyone is preparing for their final exams.. n so m i.. i have been doing the so-called 'hardcore' continuous studying for the past few days.. trying to nail thermofluids n do the past papers.. but to no avail. the exam questions are extremely difficult. it drives me to the point of being stressed out every night before i sleep.. but i know how to even things out.. went to the gym twice this week to exercise..
can't sleep properly for the past few days.. don't really know the reason behind this.. im assuming its the weather.. its been getting really warm in London n in my room especially.. with temperatures hitting up to 23ish degrees. its steaming, considering tat there is no air-con here unlike brunei where i get to have cool air in a click of a button.
Watched a movie called 'The Eye', starring Jessica Alba as the main actor who was blind, in my hall on nigel's laptop. It's an supposedly a horror movie, but i didn't find it any scary.. well maybe its just me..
As for now, i better get going. i need some sleep!
