I would guess it's a combo of both. At day 5 you are still possibly in the acute withdrawal phase. Instead of drinking make sure you get something good to eat, something to drink and some rest after work. Try concentrating on the task you have at hand workwise and don't really worry about what others are doing - you can't control that anyway.
Also remember that if you drink you pretty much reset your withdrawals back to square one. Day one sucks much worse than annoying people at work. Here's a refresher if you don't remember
