# Keep a headache diary

Canonical: https://godspeedmissioncontrol.com/guide/track-headaches

Nothing to set up: a **Headaches** tracker appears on the **Trackers** shelf in **Collections** with your first entry.

## Note a headache

1. Say when it started and what else you know:

   ```text
   headache since 6:30, right side, pounding, 6 of 10
   ```

   A reply such as:

   ```text
   Tracked: since 06:30, still going (5 h 54 min), pain 6, right, pounding.
   ```

   Without a pain number, it asks once: "How strong, 1 to 10?"

2. Say what you took, if anything: `took two painkillers 20 minutes ago`.

3. When it is gone, say `headache over`.

A headache that is already over fits in one message: "I had a headache this morning from 6:30 to 9:30". To remove an entry made by mistake, say `delete that`.

## Ask about the pattern

- `How often did I have headaches?`
- `Any pattern?`
- `How many painkiller days this month?`

The answer is a few lines with the numbers. With fewer than ten headaches, it calls a pattern a first look, and it never says one thing causes another.

## What it does and does not do

- Pain is only ever a number you gave.
- It gives no advice and no tips.
- One exception: from the 10th painkiller day in 30 days, it adds this line, at most once a week:

  ```text
  That is painkiller day 10 in 30. On 10 or more days a month, combination painkillers can start causing headaches themselves.
  ```
