I have read about people taking Ambien or other sleep RX doing weird things like cooking and shopping. I always thought I'd love it if I took it and got up and cleaned the whole house without knowing about it!
Seriously, I had plans to do some Spring cleaning, then it got warm. That was my excuse for a while. I like the idea of setting a timer and just cleaning any spot for 10 minutes. You'll find yourself going past the timer and "getting it done"
