Re: What is it about tap water.....
I have been drinking good quality spring water (haha) for about 20 years now. I got on the band wagon early. I live in a city famous for good tasting city water (haha). I used it for showering of course, and cooking, but rarely drank it. In the last couple of years only, the smell of chlorine was horrible. Before that, it actually wasn't bad.
Now, I just moved and have a well. I have a good conditioner, but I am now fearful of bacteria and cyst in what water. I would not drink it anyway, I buy purfied (haha) 5 gal jugs for a cooler. It's probably bottled from the city water I just left. I use a water filter pitcher, which does not do much I'm sure. I can't afford anything else, maybe someday.
I'm not answering your question, that is strange thing that happens to you. Yeah, it's good to avoid it, but sometimes you can't help it. Do you have any adverse effects swimming in a chlorinated pool?
