You said yes because you are kind, capable, and you did not want to disappoint anyone. Then the aftertaste arrived: regret, resentment, and that heavy feeling of being booked beyond your own limits. Stop the People-Pleasing Hangover is a practical guide to what happens after an unwanted yes, and what you can do next without burning bridges or burning out. Leila Marbrook helps you run a clear review of the commitment you made, so you can separate what was asked from what you assumed, and identify what is still negotiable. You will learn how to do renegotiating commitments with calm, direct language, how to face guilt and obligation without folding, and how to repair trust when plans need to change. Along the way, you will understand why resentment is not a moral failure but useful information, and how an honest resentment reset can point you towards your next boundary. This book is for anyone doing too much because saying no feels like conflict: the reliable colleague stuck with extra work, the friend who always organises, the adult child carrying the family logistics, the partner who absorbs the emotional labour. With tools for boundary setting, realistic workplace boundaries and family boundaries, and simple saying no scripts, you will build a repeatable system for making a clean yes only when you truly mean it. The result is not a new personality. It is a new process: fewer hangovers, clearer commitments, and more of your life returned to you.
