Any nurses on here that work 12 hour shift on nights?

I work 3 12s on nights. How r u handling night shift? On my days off all I do is sleep cause I'm so exhausted from working nights. I'm thinking about switching to days so I can have a "normal" schedule. But the unit I work on is crazy busy during days and I'm afraid I won't get enough breaks as I do on nights. I also read night shift increases the risk for miscarriages and LBWs. What's your say on this? Someone help me decide. Thanks.
