I'm definitely not trying to be argumentative. But it's interesting to look at what seems like an opposing viewpoint on this. Here's a psychologist who said that the body reacts by developing an _increased tolerance_ to drugs like caffeine and heroin, based on the time of day and situation in which those drugs are taken: http://blog.sethroberts.net/2014/02/04/philip-seymour-hoffmans-death-from-heroin-why/ http://blog.sethroberts.net/2014/02/04/philip-seymour-hoffma... Again, I don't doubt what you're saying about the effects of caffeine on you. Not at all. I bring this up because it's an interesting counterpoint and I don't know how to resolve it. I don't know how to think about this. The original article focuses on specific immune suppressing drugs. Maybe the body behaves differently in the face of drugs like caffeine or heroin? Maybe the body reacts in one direction sometimes and the other at other times for some reason (?)
