There is no magic time frame. I am six weeks sober. I am on step one. For me step one was going to AA. I have a sponsor now and we are meeting Friday to talk through were we need to go from here.
I am one to always dive in and want the quick fix. These days I know I need to slow down. It is not a race.
I think it really depends on your sponsor and your personality to determine how to take each step and how long you need to process and complete each step.
