Clinical perspective, offered as context rather than as advice. The mechanism and the magnitude are separate questions. Agreeing that something happens says nothing about whether it happens enough to act on.

Same experience, arrived at from the opposite direction. Nothing to add that would improve it.

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

One concrete data point for the thread. 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 PharmacoVig_BOS’s answer:

What did you change at the same time, and can you separate the two now?
