I had a quick question since you've been drinking distilled for over 20 yrs.. you probably won't remember when you first started drinking.. but were you feeling a bit queasy when you started?
I recently started drinking only distilled water about a gallon a day, since that's my daily water allowance to begin with.. going from regular spring water and sometimes tap with a filter. and I find the taste with distilled better as I got used to it.. kinda crisper? I don't know but I felt a bit.. 'sick' I wouldn't even use the word sick.. but yeah.
I've read both neg and pos things about the water.. but I'm not one to really care as I use my body to guide me, as you said theres pros and cons with everything.
