From the other side of the consultation, briefly. The distinction that resolves most of these threads is between what is true on average and what is true for one person. Both are real; they answer different questions and get quoted as if they were the same one.
If somebody has the primary source to hand I would rather cite it than paraphrase it.

Adding a me-too, because a thread of one person's experience is not much use. I had assumed I was the exception until I read this.

Coming at LindaRN_retired’s question from a different direction. The version of this that has an answer is narrower than the version being asked. Narrow it and it becomes tractable; leave it broad and the thread will produce nine confident and incompatible replies.
Worth separating that from compounded supply, which this thread keeps folding into the same question. They behave differently and the advice does not transfer.

Happy to go further on any of that.
Following on from LindaRN_retired — and this may be the naive question:
How much of the between-person variation is pharmacokinetic and how much is just adherence measured badly?
