I don't see why anyone should doubt your observations about the quality of your sleep over time. You've surely paid closer attention than they have, what with it being your sleep. Causality is harder to prove though. Was it really long-term conditioning through melatonin and Coq10? I moved to a new apartment recently and my sleep improved. I thought it might be because of a brand new, very clean aircon. Then my sleep got worse again with nothing else obvious changing. Who knows what confounding variables may exist. Stress, diet, season, etc.

As for the theory of placebo effect (where a placebo actually has some type of therapeutic impact), I don't think we've really concluded whether it exists or not -- I'm not a doctor but my understanding is that there is evidence in both directions and the debate is ongoing.

I did a lot of other things too. That wasn't all I did.

But I was able to successfully alter my circadian rhythm on short notice when I worked the night shift and had to occasionally show up for the day shift by using Co q 10 in the morning and melatonin at night and making no other changes. So I'm absolutely certain this combo can move the needle on the circadian rhythm in specific.
