I started my "nurse" career as a LPN in 2009 and went on to earn my RN in May 2011. I noticed, almost immediately, how easy the pounds began to pile on once I started in my new role. When I started nursing school in 2008 I weighed 150 lb. and had more muscle mass. I'm now almost 40 lbs heavier. I'm depressed and tired all the time. What has this career done to me?
