FWIW I have used Melatonin and Diphenhydramine for years.

I have never "developed a tolerance" nor "upped my dosage" and they still work just fine for me. I do not use them every night but many nights a week without a doubt.

You can get away with almost anything when you are still relatively young, but that changes as you get a little older and your body becomes less efficient at metabolizing and clearing various substances. It's not a good idea for the longer term.

And of course there are exceptions to every rule. Keith Richards seems to have done OK with heroin through his 70s or so, but that does not make it a good example to follow.
