Will you be completely sober as far as blood alcohol in 12 hours?

I need to be at work at 12 hours. Drank a 26 ounce bottle of whiskey tonight and need to be dead sober before reporting to work in 12 hours. For context I drank the bottle in about 5 hours total. If I sleep 8-9 hours and then report to work will I be fully sober? By fully sober I mean blow a 0.0 if required? Thanks.
