You know that maybe you are experiencing a placebo effect too? You want to think it didn't get any better so your mind won't recognize any improvements - self-fulfilling prophecy.Sigh. This is pointless. Thats the entire point of it being a placebo. The mind over matter. Placebo effect affects everyone.
Think and believe what you want. But don't go around calling people uniformed.
As you said, don't go around and tell people there are no improvements.
