I can't sleep (unless I'm extremely deprived, at which point I'm really just passing out) until after I've done the unwind things mentioned in the article and have been away from work for ~3 hours. It doesn't matter when I stop working, I cannot sleep until 3 hours has passed. I've tried, I lay in bed for 3 hours minus commute time.
