Friday night - This is when things started going downhill. I tried to sleep right at sunset but couldn't, probably because I slept late the previous nights and wasn't used to going to bed that early. I tossed and turned for the next few hours and started hiking at 2 AM. I don't know whether I got any sleep that night.
Did you sleep well at the Mammoth hotel? I never sleep much at the campground either. I think that is normal. I wouldn't worry about getting much sleep the night before Whitney. It's the night(s) before that which matter more. That's why I stay at Mammoth myself. I can sleep good at altitude if it's on a hotel bed.
