Seems like my body clock has aligned itself to normal hours now - I've actually started sleeping before midnight. Next target is to see if I can bring the sleep time closer to 11PM. Hopefully I can maintain this schedule leading up to the first day at my new job.
Oh, and I need to get a haircut at some stage. My hair was a mess on the first day at my previous job - was planning to go to the salon in the morning so that my hair would be at its best on day one, unfortunately I couldn't find a single salon in my area open at that time. And just my luck, they took a photo of me for my ID card, and my streak of bad ID photos continued.
