Well when I was drinking coffee than I was first 30 minutes like "Wohooo lets do it!" and after that... "Let me sleep..." This problem quite escalated during exams at university, when I was trying not to sleep for two days and learn as much stuff as I can... oh my I think my record was something like 12 coffes in about 8 hours and after exam I felt that I could die any minute.... aaah memories.
