God, I'm at work and am *so* tired. I'm trying to look up ion selective pH meters and am drawing a complete blank. For *pH meters*. If I can't find a friggin' pH meter, what use am I?
Oh god, I got home and was ready to go to bed at 6:30. In fact I *did* I took a nap for an hour or so and I'm *still* ready to go back to sleep. This seriously sucks.
