Water.....

Okay. I've reached 5 glasses today. That is more than ever. It's getting better but such a struggle. So I ask myself why am I so worried about WHAT water I drink.....why can't it be enough that I am drinking it? I know...I know.....chemicals...BUT. I am still way confused as to the difference between the tap water and the bottled water. Such a contraversy. PLUS we are selling our house. So it would be a waste to get a filter for the house now....we will do so when we move. But in the meantime, is it really best to be drinking the bottled water when I don't understand the difference between the brands out there- I know spring is best, but how do I know it's really SPRING and not tap? Someone told me to boil it- would that really get the chlorine, etc. out of it or is boiling just for the bacteria?

I am SO CONFUSED!
