The tiredness is the worst part. My sleeping patterns seem normal but I have not really been awake for 4 days. Each day I feel more and more sleepy. To combat it I've tried exercise, drinking lots of water, cold water splashed on my face, talking louder than usual and shaking my head like a wet dog. Not scientific... but something has to be tried.
Other side effects include hightened intolerance for stupidity, the sudden need for 3PM naps and walking slowly by the coffee shops to smell that which must not be named.
Thanks to Sanson for the only good advice I've recieved. Others have offered alternative addictions but I will pass on those for now.
PS I've also had to edit this post 4 times.
