obviously make sure it's the kind of glycerin ok for consumption...
Yup it's from the hippie-food store so it should be ok.
In the late 70's/early 80's, Farllon offered a first-stage attachment for this purpose. It screwed into the first stage and you attached the second to that (lengthening the hose length by 5"). You unscrewed a metal plug & o-ring and added distilled water. This increased the humidity of the incoming air and prevented dry-mouth. Of course this was only safe in warm water as it lead to rapid regulator icing in cold water.![]()
That last line is a gem
