Early to Bed, Early to Rise?

Yesterday I was on the phone with Gigi while driving home from work. She was feeding the dogs and mentioned that she was very tired and was going to bed shortly. This was at 4:10 p.m.! Since she's a late sleeper I asked her what time she woke up. She wouldn't answer but she said she slept in (which translates to 11-11:30 a.m.) but had gotten a pedicure that afternoon. Basically, she feels that a pedicure takes a lot out of you so it's best just to go to bed early.
