Very common in people with c o p d I have found

I too always need to read before I sleep or even nap...it calms me down...takes me on thrilling journeys...light does not bother me...when I need to sleep nothing else bothers me...and I can't sleep without my little Malti-poo...Chiquita...she feels the same way about sleeping...needs to be right with her mummy...she's my life line...I'm on oxygen when sleeping and walking around and doing the chores I still can do...When I'm just sitting, on my computer or watching a movie I don't need my oxygen unless I'm really stressed about something...(like the election) had me stressed beyond stress...now it's over...I feel so thrilled and more relaxed...

The bedroom needs to be quiet when going to bed, no radio:TV. Rooms needs to be completely dark, even the smallest light can cause sleeplessness . No tea/coffee, or any form of alcohol. Try reading a book for a while before sleeping. Definitely go to the loo as well. Good luck.
Stay safe! MERRY CHRISTMAS

We pretty much all suffer from it. I don't know what is with 2 am, but it seems common time for many of us to wake up. Seems impossible to fall asleep again. We all walk around tired and no energy
