Hill's monitoring rule addresses a perception problem: when people become depressed or anxious, they may explain the feeling through stories about a boss, partner, or life circumstances rather than recognize a possible medication-linked change. The method creates two signals. First, the user notes a baseline and watches their own mood after starting hormonal birth control. Second, a trusted person is told about the change and asked to flag visible differences such as seeming low, off, anxious, or unlike oneself. Regular check-ins make the observation repeatable rather than relying on memory after a crisis. Hill emphasizes this especially for users aged 19 and younger, whom she describes as having a higher risk of mental-health side effects. Any concerning change should trigger professional assessment rather than self-diagnosis.
Origin
Dr. Sarah Hill gives this monitoring advice on Habits & Hustle while discussing depression and anxiety risks associated with hormonal birth control.
Core principles
- 01Mood changes can be difficult to recognize from inside them
- 02A trusted observer can detect changes the user rationalizes away
- 03Starting a medication creates a useful monitoring baseline
- 04Young users warrant particular care because their brains are still developing
How to run it
- 1
Capture a baseline
Before or when starting the medication, write down your typical mood, energy, sleep, anxiety, and behaviour. This gives later observations something concrete to compare against.
Pro tip Keep the baseline short enough to review weekly.
- 2
Choose an observer
Tell someone you trust that you are starting hormonal birth control and want honest feedback. Pick a person who sees you often enough to notice a change.
Pro tip Agree in advance that direct feedback is welcome.
Watch out Do not rely on someone who dismisses mental-health concerns.
- 3
Name the warning signs
Ask both of you to watch for persistent low mood, unusual anxiety, withdrawal, or a marked personality change. Define the signs before they occur so they are harder to rationalize away.
Watch out Urgent or suicidal symptoms require immediate professional help.
- 4
Run regular check-ins
Compare current mood and behaviour with the baseline at a consistent interval. Record meaningful changes and when they began.
Pro tip Use the same few questions each time.
- 5
Escalate concerns
Bring significant or persistent changes to an appropriate clinician, including the timing relative to the medication change. Use the record to support the conversation rather than diagnosing yourself.
Pro tip Take the baseline and check-in notes to the appointment.
Watch out Do not stop or change prescribed medication solely from this checklist without appropriate medical guidance.
In the wild
A young woman tells her sister when she begins hormonal birth control and records her normal mood and energy. Over the following weeks, her sister notices unusual withdrawal and persistent low mood that the user had attributed only to school stress. They compare the change with the baseline and bring the timing to a clinician.
→ The possible side effect is surfaced earlier and assessed with concrete observations.
Common mistakes
Monitoring only from memory
Without a baseline, gradual changes are easy to normalize. A brief written comparison makes the signal clearer.
Explaining every feeling away
Work and relationship problems may be real, but they should not automatically exclude a medication-linked change after a new prescription.
Using the checklist as a diagnosis
The process raises a possible signal; it does not establish cause or replace clinical assessment.
Is it for you?
Best for
Someone starting hormonal birth control who wants a simple early-warning system for possible mental-health changes.
Not ideal for
It is not a substitute for medical advice, urgent mental-health support, or professional monitoring.
From the transcript
“if you go on hormonal birth control, keep an eye on yourself. Have somebody that you love keep an eye on you.”
“having somebody know that you're going on it so they can keep an eye on you is incredibly important because then they can tell you…”
“really really take care and make sure that somebody's keeping an eye on you just because the risk of developing a mental health related side…”
