For the last couple of days, I have been having great trouble sleeping at 'normal' hours. I feel it is starting to affect my work, as greater headaches are starting to climb through the painkillers.
That, however, is not the problem. I am sure I can get this issue under control soon enough, but what strategies can I employ to not have my current state of sleep deprivation show in the office? I work in an IT environment where I share a room with 7 others in a dual-island structure, so I cannot avoid sitting across people and needing to engage in casual development meetings.
