Yes, quite often. Even after sessions that are relaxed and not intense. I have driven home in tears more times than I haven't.

I also haven't figured out whether it's better to just get into something new, wondering if there is time enough for it, or try to hold it for another session. Neither feels so hot. So I have kind of given myself a limit of 20 minutes: if there are 20 minutes left then I feel like there may be enough time to get to it or to most of it, less than that I don't know.
