What? Are there people who sleep the whole night? News to me, LOL! Back when I was still working and I awoke in the middle of the night I'd close my eyes and think about pleasant things and hope to fall back asleep. If that didn't work I'd just lie still and rest my body. Been retired over 10 years and my sleep cycle is 3 hrs. asleep, 3 hrs awake so I've learned to just roll with it, do paper work, read, watch tv, have a nice cup of tea, empty the dishwasher or dryer, etc.
