I don't normally drink coffee in office. I prefer to classify myself as a social drinker (coffee as well as alcohol). no thanks to the 5-hour long project meeting today, I drank 2 full cups of coffee. at 3pm, I was struggling to keep my eyes open while trying to listen to people arguing endlessly. not a single thing entered my brain.. so I decided to get the free coffee from cafeteria, since the meeting room is just a few steps away. 10 mins after I returned to the meeting, somebody decided to buy coffee and I got my second cup.. I was very wide awake till the end of the meeting at almost 7pm. I hope I'd have no problem sleeping tonight.
