I had a cup of tea yesterday at 10am.
I was still having palpitations at midnight, and was wide awake. Didn't sleep until 1am.
Is it just me who is this crazy sensitive to caffiene? How do so many people chug coffee all day and not have any problems?
I'll never forget the time I had an energy drink at the library once when I was at uni, and had to go home shortly afterwards to lie down!
