Since I don't like the commenting options on your blog, I'm going to respond here to your melatonin experiment. Comparing two periods is statistically dangerous because so many other details might have changed between them. It is good that you are going to do two more periods, but I think you should do many trials of shorter periods, say, one week each. The drawback is that sleep has cumulative aspects.
Gwern suggests that you try smaller doses. I suggest that you try much smaller doses: 0.3mg. Or maybe cut those up.

Is there anything I can (easily) do to fix this?

The reason I am doing longish trial periods is to test the "addiction/withdrawal objection" ...
I recently came out against paleo in the open thread, and realized that I probably haven't yet heard the strongest arguments in favor of a paleo diet. So, what are said arguments?
EDIT: Or more generally, why should I eat less carbohydrates and more protein / fat?
