Early on, it helped me to get a planner, and write down tasks for the day to keep me on a healthy track. My plans for the day included a lot of basic stuff like eating breakfast which might come naturally to many, but was new to me as a recently sober person.
Normally, it looked something like this:
time on SR
breakfast
shower
work
lunch
play drums
go for a walk
chores
yoga class
dinner
I found that making a healthy routine and working through my list of healthy recovery behaviors really helped me out.
At first, I had no idea what to do with myself without drinking and smoking taking up large chunks of my time. This really helped me to be productive each day.
I don't know if something like that may help you to direct your time and energy to healthy behaviors and avoid ANY addiction-like things.
