Statistics can be just as obviously irrelevant to an individual as an anecdote to a big picture. A correlation between caffeine consumption and productivity or work well-being means nothing in case of an individual. Studies can't tell how individuals react, and I have a hard time seeing how a study would be relevant to OP in any way. OP wasn't asking for statistics, or "the big picture". Of course anecdotes from other people can't really tell how things work for OP either, but I think they were looking for experiences that might be relatable.
