Not to take away from your great efforts to solve this problem but you controlled for a few key variables in your experiment but not for the placebo effect which is one of the most important factors to rule out in such experiments.

It doesn't matter. Medicine is a lot less about proper science than we'd like to believe. It's about helping people feel better. Science is a crucial tool for that, but it doesn't always work, while random guessing sometimes does. Even the science is often supplemented with random guessing.
Eventually, you take enough random-guesses-that-worked and apply science to it. That gives you a lot more confidence to recommend it to other people. But often, confidence is all you get, rarely certainty.
While I admit that n is pretty small indeed and thus doesn't qualify for a proper and rigorous clinical experiment, the reason I mentioned the placebo effect in particular is because of the fact that some symptoms or diseases have some psychosomatic streak to them, if you will, and therefore the role of the placebo effect in these cases becomes more pronounced to research and investigate but if the OP felt way better after the treatment, that's what it all counts like you said.
It was no nitpicking or mischief on my part raising this issue :)
