Days can be quite a bit different than nights, but you'll adjust

.
Days can be more frenetic and chaotic--there are more people around; visitors, doctors, OT/PT, etc. Patients have more scheduled tests. The pay is less. Noc shift seems to have a little more comradery.
On the other hand, you get to sleep nights and that can be a big plus. I've been working nights and thinking of moving to days because I'm just always so worn out.
Go for it; if you don't like it, you can always switch back
