Hug for having a very common type of doctor, sadly.
But a win for testing anyway & keeping a food diary.
( Why do they insist on lumping us all as one, and not consider we MIGHT prefer a choice in managing such tasks ...
As
@bulkbiker puts it , you'd look at the Speedo to check your safe, right .
And as l'oreal say..."you're worth it"
Others have it right I say.
Test but make them count for something.
Continuity is the key.
I tested while making a tea.
Others once foot on floor.
Horses for courses, just make it similar each time.

You know your looking for dangers, & you won't find them blindfolded.
And after a while the dangers diminish as you spot the guilty ones, and no longer have them on your plate.
You got this.
Good luck on your journey.
