Review:
A very bored Sherlock decides to experiment with caffeine. This is not a good idea.

What a blast. Sherlock on caffeine is a riot, but even better is watching everyone trying to babysit Sherlock on caffeine. Best of all? Desperate texts from Scotland Yard detectives and Mycroft's stint of Sherlock-minding duty. Just plain fun all around.

(Note: apparently this is the first in a series; I haven't read the other story in the series, so I can't speak to its quality. If interested, there's a link at the top of the story file.)
