No, I don't have a lot of luck going back to sleep. But the times I have succeeded, I've noticed a few things. First, I'm cold. If I get hot, it's all over. Secondly, I must have an empty bladder. If not, that's all I can think about. Third, I have to be laying on my right side...my favorite side. Tricks that I use to trick myself into being sleepy is going over my prayer list, or doing easy, slow, physical therapy exercises that make me count, or trying to remember what I'd been dreaming about earlier. If none of those work, I grab a book or my phone because sometimes reading will knock me out. Sometimes meditation will calm me enough to help me sleep too. I try everything until I fall asleep, or give up and go watch TV.
