If two explanations both fit, the useful question is which one predicts something the other does not.

This matches mine closely enough to be worth saying so out loud.

There is a second half to this that has not been said yet. 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.

The figures, for anyone assembling their own picture. If you are going to change something, change one thing and give it long enough to express itself. Four weeks is the usual minimum for anything pharmacological on this board, and two weeks of data has told you almost nothing.

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

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

This is where I part company with the consensus forming above. I would resist the confidence. Half of what this board was certain about two years ago has since been quietly dropped, and nobody went back to correct the threads.
