Quitting more than one thing, or planning to? Add everything you are stopping, from coffee and vapes to sugar, alcohol or a prescription, and enter when you stopped or plan to. You will see the typical phase ranges that each article’s cited sources describe, placed on your dates and shown side by side, a warning if anything on your list can be dangerous to stop, and a checklist of things that may make it easier, each with its source. These are ranges from published sources, not a forecast of how you will feel.
Stopping something dangerous?
Stopping alcohol, benzodiazepines, barbiturates, opioids, GHB or gabapentin-type medicines suddenly can be life-threatening and needs medical supervision. The calculator cannot tell you whether it is safe to stop, or when a dangerous period is over. Never stop a prescription suddenly without talking to your prescriber.

1. What are you stopping?
Your picks stay in this browser. We don't receive or save them. Details
The calculator runs in your browser. What you pick and the dates you enter are not sent to our server or anyone else, and are not saved by us. This page has no ads and no analytics; it loads only files from our own site, including a visit counter that receives no details about your picks.
Your picks are kept in the address bar after the # sign so the page can be bookmarked or shared. Browsers do not send that part to websites, but it stays in your browser history, and anyone you send the link to can see what you picked.
Downloaded images, printouts and copied text also show your picks. If you used the date picker on one of our articles, that date is saved in this browser only (not sent to us) and is used to pre-fill the date here. Privacy policy

2. Source ranges on your dates
How to read this: each row shows the typical phase ranges described by that article's cited sources, placed on the date you entered. It is not a forecast for you and not a diagnosis. Being past a marker or a range does not mean symptoms or a dangerous period are over. Some substances have no chart because the sources do not establish a timeline.
Tap or hover a bar for the article's wording and symptoms. Each row starts from the time you entered. Colours show the severity the article gives each phase; nothing is added up across rows.
3. Things that may make it easier
Only tips from our articles or from the linked public-health pages (such as the NHS, NIH institutes and the FDA), each with its source. Linking to a source does not mean it reviewed or endorses this site. Duplicates are merged and grouped by theme.
These are typical ranges from published sources, not a prediction for you and not medical advice. Everyone is different, and the timelines come from our articles, which are AI-assisted and not yet medically reviewed. Talk to a doctor or pharmacist before you stop or change any medication. In an emergency call 911. Medical disclaimer · How we write and review
How the calculator works
- Each row uses the phase-by-phase timeline from our article on that substance, the same data as the “When did you last use or take it?” picker on each article. A timeline is only charted when the article lists cited sources for it; each row shows those sources and what type they are (for example a clinical guideline, drug label, clinical reference chapter, research paper or patient information page).
- Bars are coloured by how severe that phase usually is. The diamond marks the peak range, the dotted line marks where the sources’ range ends, and the “Now” line shows today’s date. Being past a line does not mean symptoms or risks are over, and it is not a diagnosis.
- Each substance has its own row. Rows are never added together, and overlapping bars do not assess how substances interact or whether it is safe to stop several at once.
- How much and how long you used can change withdrawal, but our sources do not give numbers for this, so the chart is not adjusted. Where an article explains it, we show that explanation instead.
- Some timelines are not well established (for example kava or PAWS). These show a link to the article instead of a chart.
