Went to bed at 1000, but woke up at 1430. A total sleep of 4 and a half hour, not good. I am used to sleep roughly 7 hours and sometimes more. I feel dizzy and needs coffie, however I still feel wasted as if I had stayed awake while I should have been sleeping. Last night we switched to summer time which has displaced my sleeping-pattern by one hour in the wrong direction. I am beginning to consider when to force a transition upon myself, so normalization can occur. The temperature is 30.7 celcius inside my appartment, because its being hit by direct sunlight. Maybe the heat woke me up?
