The point i was trying to make is this: if someone is going to begin a habit / ritual, to do a certain activity/ process, then certain factors have to be constant, if he or she begins to take pills in a mock DAT seating and gets accustomed to this habit/ritual, and for the REAL DAT his or her constants are not not constant, he or she might get nervous/anxious for not being able to accomplish the habit/ritual; the pill taking.
to answer your question, smarty pants, yes i drink coffee, 3x a day doesn't matter before or after the activity. As a dental assistant i do like to take a swig before going into big surgeries, if no coffee is available, no problem, big gulp of water.
as for poor analogy, i think it was a good analogy. judgmental?, no, but an opinion/statement, yes.
