Clinical perspective, offered as context rather than as advice. It is worth asking what the claim would look like if it were false. If nothing would look different, it is not a claim about the world and no amount of discussion will settle it.

Second this. The detail I would add is minor and it is already implied above.

Adding the part of the answer the thread has not reached. It helps to ask what evidence would change your mind before you look at any. If nothing would, the discussion is not about evidence, and it is better to say so early than to spend nine posts discovering it.

I would rather be corrected than agreed with, if it comes to it.

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.

Following on from Dr.MetabolicMD — and this may be the naive question:

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