Has this been characterized in literature to any significant extent? This isn't a "challenging" question btw, I hear it repeated but wonder to what extent it's actually true vs. people's later perceptions coloring it and/or odd internal perception. The latter I think is possible because I've read anecdotes from people who say they don't feel much, yet they go from demotivated to get up and do something to sudden motivation to do lots of different things besides what they got up to do, which reads to me as overshooting the mark in terms of effect if not in matching patient's expectations of "how it should feel".
