> having some slight lower back soreness and am peeing like crazy, but that may be because i'm over compensating by drinking a ton of water so i don't dehydrate
I have a friend who has chronic kidney problems (one is deformed, they both carry "a constellation" of stones). She needs a regular moderate intake of water, but NOT overdo it. If she drinks too much, it increases her kidney pain.
Unless you are trying to flush a stone, there is no reason to drink a ton of water.
Good luck on the MR, and in Mexico. Hope you will post reports of both!
