My order from Lazada arrived just now. The pack has "natural MELATONIN" in big letters, which is why I ordered it. On examining the small print on this Made In Thailand product (easily recognisable by the American Stars & Stripes flag on the pack) I am somehow neither disappointed nor shocked to see that Melatonin is conspicuous by its absence. Yup! (or rather nope) when they say "natural melatonin" they mean "contains no melatonin at all, in fact completely free of the substance" which now seems perfectly logical. "This Is Thailand" after all, the country I love and have made my home.
I shall try a capsule tonight, with its usual cocktail of "natural ingredients" and "vitamins" you'd need a Hubble telescope to detect, but I expect nothing, and I'm sure I shan't be disappointed. If you can bear the excitement, I will be posting a live update to this thread, probably about 3:00 a.m., so do check back.
(Incidentally, I have no trouble at all falling asleep, I'm not insomniac in that way, it's the rhythm of sleep that's somehow lost with age - as with so many things - I wake up after a couple of hours sleep, stare at the dogs for a while, go to the bathroom, back to sleep - rinse and repeat. Melatonin definitely helped me glide over the shallows back into satisfying sleep.)
