I guess I don't relate to recovery being a Sisyphean task: I did this, the Gods did not set me to it. I can stop whenever I want. (Drinking myself to death is still an option.) And when I stop pushing the rock does not roll backwards. In fact, sometimes not pushing is exactly the right thing for me to do. The rock just coasts along under its own inertia.
The first few weeks were a battle. I really enjoyed having the demon of addiction adversary to battle against, and I missed the struggle when it was gone. After that it was a process of accepting things as they are. There is no rock, no demon, just me.
