  How effectively do we adhere to nudges and interventions that help us control
our online browsing habits? If we have a temporary lapse and disable the
behavior change system, do we later resume our adherence, or has the dam
broken? In this paper, we investigate these questions through log analyses of
8,000+ users on HabitLab, a behavior change platform that helps users reduce
their time online. We find that, while users typically begin with
high-challenge interventions, over time they allow themselves to slip into
easier and easier interventions. Despite this, many still expect to return to
the harder interventions imminently: they repeatedly choose to be asked to
change difficulty again on the next visit, declining to have the system save
their preference for easy interventions.
