I'm not sure 🤔 I think in theory it's fine to drink distilled water as it's just water. But it's missing some of the important minerals that give it its thirst quenching palatability. I'd rather drink Seattle tap water which is probably among the best in the nation, well, it used to be at least back in the 90s. I've had some crap tap water in places like San Diego, Texas, SC and Florida. Has too soft of a mouth feel and annoyingly stale taste. Glacier water is where it's at 🤤
