I've said this before - but this is just a reminder. I'll be breaking BOTL over time in order to get it into a far better place. Just be patient if you can't reach us! We'll be back
Flushing rarely ever wakes me up.....it's finding my way to the bathroom in the dark that's the biggest problem; stubbing a toe on the footboard of the bed will wake you up quick!
I read that the only thing that will keep you awake once you get up in the middle of the night are lights. I generally go to the bathroom most nights at 2am or so (sorry if that's TMI). I don't turn on any lights, always flush and am back to sleep within 5 minutes.
