Mind you, pointing out placebo could be useful if the OP made the claim that their solution could cure a disease or something (such claims could discourage someone from getting effective treatment).
You are likely aware of this already, but for others readers, it's important to know that placebos are still effective even when you know they are placebo. The term is "open-label placebo".
I wouldn't be surprised if you felt better even before you took your first dose; I can imagine you started feeling better just having a prescription in hand.
One of the biggest parts of placebo is going through the motions, whether you believe it or not. The original commentor appears to be aware that their approach may not have any scientific basis so mentioning the potential of placebo is fine.
