A personal story, not medical advice.
Everything on Quit in One Day and in the book Out of the Hell of Addiction is the lived experience of one person, written under the pen name Adam K. The author is not a doctor, a psychologist or an addiction specialist.
Nothing here is medical, psychological or professional advice, a diagnosis or a treatment plan, and it is not a substitute for one. What worked for the author may not work for you. Quitting “in one day” describes the author’s own experience; it is not a promise of any result.
See a doctor if…
- you also use alcohol, pills, prescription medication or other drugs;
- you have a heart condition or a mental-health condition;
- you feel strong anxiety, sadness or other symptoms after stopping.
