I don't usually get up to go to the bathroom. I try not to take in fluids particularly before bedtime, in order to avoid that.
I do turn over quite a few times during the night. Usually I don't really wake up but I'm conscious of turning over, at least I think I am whenever I do that.
Sometimes I sleep a lot better than others. Many times I wake up and decide to stop trying to sleep and get up and do things for a while, then go back to sleep when I feel sleepy again. I prefer not to do that, though. I don't have trouble getting to sleep, almost ever when I first hit the sack. My only sleep problems are when I wake up and can't get back to sleep shortly thereafter.
