Went from corporate nightmare to remote freelancer and I miss structure

I know everyone dreams about leaving their soul-crushing office job and I finally did it last year. I'm my own boss, work from home, no commute. Should be living the dream right? Weird thing is I kind of miss the structure. I miss having coworkers to grab lunch with. Miss the forced routine. Now I'm working in my pajamas at 11pm on projects and sleeping until 9am when I actually have morning soccer games with my kids. The flexibility is amazing but I'm realizing I need more discipline than I thought. Thinking about restructuring my whole setup but not sure how.
