Interesting. Without going to those extremes I have experienced sometimes, when playing more than usual to reach a rakeback milestone, how it affected me negatively, so years ago I decided not to do it, always playing a moderate number of hours that I know it feels good and does not negatively affect my mood.

In this graph I can understand how for example when I see people who play slots in person and do not stop, they have a behavior similar to that of the junkie who seeks the high of the first shot but never gets it, but one that gives him less satisfaction, while sinking him in the hole.

The graph is very illustrative.
