Adding the numbers, since they settle part of this. 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.

Following on from traveltech_sara — and this may be the naive question:

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

Moderator note: good thread. Keeping it here rather than moving it, because the question is general enough to be useful. Report rather than reply if it drifts again.

Correct as far as it goes. The part it does not cover is what to do when the honest answer is "not enough data", which is more often than anyone likes.

This answered a question I did not know how to ask. Adding it to my notes with a link back to this thread.
