kontextmaschine:

So without a default bad mood->negative mentality, without surplus energy being diverted into catastrophizing and cointerplanning, and with my blood pressure (and maybe strength/volume of heart pumps?) significantly reduced it’s actually a lot harder to identify where my caffeine level is at to calibrate consumption

The main thing I can tell seems to be my breathing being slightly heavier, maybe cause I need more air to oxygenate the additional volume of blood from the increased heart rate
