You can drink 10 bottles of water and still feel this way. Even vegetarians are craving a Cheeseburger and a side of fries. Don't feel sick, but something is definitely amiss. The coffee you chug to try and remain focused is only exacerbating your rumbling gut, which is craving a full English breakfast. Last night has wreaked havoc on your bowels and even though you have a nice demeanor about the office, you are costing your employer valuable money because all you really can handle is aimlessly surfing the net and writing junk e-mails.
Stomach feels crappy.
You are definitely a space cadet and so not productive. Life would be better right now if you were in your bed with a dozen donuts and a liter of coke watching Good Morning with Richard and Judy. You have lost the will to live. Your boss has already lambasted you for being late and has given you a lecture for reeking of booze. Home time, 2.
