Articles
Practical articles on mindful alcohol observation — without lecturing or medical promises. Here you will find short guides on grams of pure alcohol, standard drinks, weekly limits, local-first privacy, sleep patterns, and why apps should not decide whether you can drive.
Each text is written for calm habit tracking: numbers as reference points, not verdicts. If you want a tool that puts this into practice on your phone — with entries stored locally and no account required — see the QS AlcoRhythm product page.
The articles complement the app; they do not replace a doctor's advice or individual health guidance. Sources are linked at the bottom of each piece; we review them periodically so examples stay aligned with current public health education.
