No, I didn't miss that. It was those very same things you just included from both his post and yours that created my post. I was just saying that I understood what he stated differently. Apparently he drinks it for systemic health benefits, and because he likes it. I didn't gather that he drinks it to whiten his teeth.
But I do agree with your advice, white tiger. It's strong stuff. If I want to drink some lemon (in room temperature water) I mix it in water, chug-a-lug (avoiding the teeth) and then rinse with plain water. Otherwise, if I want it for taste, I only put a small amount.
