I just went back really quickly and checked. The only scientific statement I made is that there's no particular scientific evidence that cough syrup in normal doses is bad, which is true to the best of my knowledge. It was shut down due to a lack of scientific evidence of safety, but I'm perfectly satisfied with the decades of safe use (at correct doses) prior to that decision. Had the Feds stopped usage because at normal doses they encountered some problems in some children, I'd have come to different conclusions, but to the best of my problems this case has not occurred (beyond possibly low allergy levels, which you just can't paralyze yourself over, just about everything has someone allergic/reactive to it). And an encouragement to find out what the real reasons are behind the opaque advice and think for yourself. I never claimed that the fact that it worked once (or, actually, twice, but I didn't mention that; we actually do not reach straight for the medicine in general but when the child is on their third day of sleep deprivation the balances change, and again note that when I say the child here I mean it; we were trading off and actually we were well-rested overall) proved anything "scientifically".

(Incidentally, the same appears to be true of Benedryl, for what it's worth.)

I think your detectors for anti-scientific crackpot triggered, which I understand because someone who actually deeply understands science and its limits can accidentally trigger them sometimes where the science is particularly iffy or thinner than advertised.
