I've never seen anything like this...the strip actually got soooo dark it looks black. I've been drinking water today like it is going out of style (I've been so thirsty) I've felt completely run down today, like the inside of me was going really really fast and the outside of me wants to sleep. So over the past hour I've drank another quart of water (hoping that that will make the strips lighter) it is lighter but not by much. Should I be concerned?
