I hesitate to contribute anecdotal evidence but my experience has been very similar. In college, I routinely took 200 mg caffeine pills and I would always stop cold turkey after exams, when I was usually hitting about 300 mg a day. Definitely felt the alertness almost every time I consumed more caffeine and, surprisingly, never had any withdrawal symptoms outside of drowsiness.
