new grad thinking of switching from nights to days

You guys may remember me posting a few months back about starting as a new grad on an inpatient psych unit. I love my job, my co-workers and my patients...but not so much my shift. I've always been more of a night owl, so when I was given the choice between days and nights, I took nights. I've been on orientation for 8 weeks now and don't really see much of a challenge on nights. Sure 10P med pass gets a little hairy, but most our admissions come in on day/evening shift, day shift does rounds with the psychiatrists and there's more to do. I stayed over for 4 hours one day last week from 7a-11a because my NM was in a pinch and I realized that I could handle day shift. I had a big fear when I first started that I wouldn't make it on day shift because it's too busy and hectic and I'd make mistakes but now I feel like I'm just playing it too safe and doubting my own capabilities. I think there's an opening on days and I'd like to talk to my NM about how I'm feeling but I'm not quite sure what to say. Can anyone else relate to being a night owl but liking the busyness of day shift?
