Adding the clinical framing, because it changes how the question reads. Most of what circulates confidently in this community traces back to one summary of one study, and the qualifier was dropped somewhere in the third retelling.

Adding a me-too, because a thread of one person's experience is not much use. Posting only so the count is not one.

Coming at KevinCompounds’s question from a different direction. It helps to say which part of this you are uncertain about. A precise question gets a precise answer; a general one gets everybody’s favourite anecdote.

One concrete data point for the thread. Keep the original post as written when you update it, and add the correction underneath. An edited-away mistake is invisible to the next person who makes it.

One thing that is still open after KevinCompounds’s answer:

How long did you give it before you decided it was working?
