off (one's) back
No longer a source of constant stress, anxiety, aggravation, or pressure. To be honest, it's a bit of relief having all that fame off my back. It just felt like I was under constant scrutiny no matter where I went or what I did. Would you get off my back? I'm going to mow the lawn after lunch.
off (someone's) back
No longer nagging or urging someone to do something.
