The popular framing is a "dopamine detox": starve yourself of stimulation for a few days and reset your brain to factory settings. It sells well. It is also scientifically wrong.
Dopamine is not a toxin, and you can't flush it out. It's a signaling molecule that drives wanting and pursuit, the reaching-for, not the enjoying. You need it to get out of bed. A "detox" that framed it as poison was never going to work, because it misnamed the thing it was fighting.
The real target isn't a chemical. It's a learned loop that fires faster than you can think. This workbook trains you to catch that loop and interrupt it. That's a skill, not a cleanse, which is why it takes reps, and why it lasts.
