I work on batches of 2-4 pages at once so it's hard to tell exactly how much I'd get done per day. I generally manage to do one page of inks, or one of flat colours, or three of shading if I get on with it when i get home.
I'm at work 8:30am-5:30pm every day except weekends, so when i get home on a GOOD day I'll be non-stop drawing from 6pm-11:30pm (I don't eat dinner)
On a bad day (ie. it's been a long day and I'm exhausted) I'll generally work from 8:30pm-11pm.
Weekends I tend to reserve for sorting out stuff I've let build up over the week - I'll prioritise laundry, cleaning, etc. I rarely work on comics over the weekend to be honest, I spend that free time working on other projects - I make fursuits so I'll have a day on that rather than the comic.
But I'm fairly lucky in that I don't have a social life, I don't go out, it takes very little time to get to/from work, and I have very little to do with myself other than draw so I can just sit down and go for it when I get home.
