I did confirm it was staying asleep, I set it up to toggle a pin in a loop and it didn't toggle. I also need to rescind the observation I made about calling that function. I was making multiple changes in the sketches before finishing up at work and the last change I made before calling that function was create an instance using pins 0 and 1 instead of 8 and 9 just to see what would happen. I think that in combination with the function dropped the power. I'm going to try it again after dinner but if that's the case it may be related to the pin change interrupts. Which kind of sucks because I wanted to use one to be able to wake up from a low battery alert.
