37 days into quitting smoking and breathing exercises have been a huge help for the craving spikes. a simple terminal tool for paced breathing actually makes a lot of sense - when the craving hits at 3pm and youre staring at a screen anyway, having it right there in the terminal is way less friction than pulling out a phone app. starred.
