This is a public service announcement: Drink your water.
If you've ever had a kidney stone attack I don't need to say anything more you completely understand the night of hell I just endured. If you haven't lets put it this way I can't imagine pain greater if I was a Filet Mignon and a pack of hungry dogs got a hold of me. We're talking mind numbing pain.
I've been slacking on my water lately and sure enough last night as my urine output began to cease to a drip and the familiar lower flank pain was starting I knew I had brought this on myself. I planted myself in the bathroom where I writhed in pain and puked for the next 12+ hours. I'm just starting to emerge now.
So yeah drink your water.
