I know there are certain sleeping pills that you can take but have no idea which ones.
I know what you mean by wanting the energy. I didn't sleep a good night for the few days before labour and obviously not afterward either. I didn't know someone could function so much on such little sleep.
This may sound stupid but to help me get a lil more sleep I stop drinking any liquids by 7:30 that way I don't wake up 5 times a night, it's usually 3 now! That helps me a lil! But to get comfortable I can't, I'm constantly tossing and turning!
