You walk into work swallowing as many mints as possible, trying to keep your hair looking groomed and focusing straight ahead so nobody notices you are still swaying slightly. You tell colleagues that 'I was home by 11pm!' and you're just 'very tired' that's why you keep yawning and reaching for your sixth cup of coffee before lunch. Truth is you only just managed to get your keys in the front door less than five hours ago. Party animal.
