Had a shed load of shite with my back, one tip is to sit on ya bed for a minute when you wake up, gives your discs time to compress gently, hard bed is old wives tale, medium is much better, and as well as lifting correctly, watch your posture when you twist and turn.
If your back does go, i find it a bit of relive to lay on my back with legs bent at 90o and feet on sofa or table.
Other than that, give up work and take life easy.
