You'll find the answer to your question here in lesson 1. Wherever you want to draw a smooth flowing line, including sausage forms and additional masses, you should be engaging your whole arm. For textural details you can draw from your wrist.
I'd like you to carefully read this section about the path of least resistance. If you've taken a 6 month break from Drawabox, and been drawing from your wrist the whole time, it is going to feel pretty rough switching back to drawing from your shoulder. Just because it is difficult does not mean you should avoid it. Be patient with yourself, make sure you're doing your warmups (and including exercises you find challenging in your warmups). Remember drawing large (making full use of the space on the page) will make it easier to engage your whole arm, and as always make full use of the ghosting method for every line.
