Suggestions
Use additional descriptors to track more factors you wouldn't add individually
For mood, we can add descriptive keywords and it can be useful to see how certain factors affect our mood. E.g. “Low sleep makes you feel grumpy”.
My suggestion is something similar for symptoms. So if I have very occasionally blocked nose it’s not something I’ll track but having it included allows me to track the prevalence of it alongside consistent factors. Sometimes a symptom isn’t consistent enough that we assume we have a trigger for it but could an intolerance for example.
