If i drank a pint of captain morgan within a 4 hour period from 6pm-10pm and drank a lot of water will i be able to pass a breathalizer at 8am?

Stop this: I believe we've heard from you a few days ago with a similar question. What you're suggesting is a very bad idea. You shouldn't drink this much hard liquor this fast, or then plan to beat a breathalyzer. You're in your physical and intellectual prime. There are so many other things you could be doing that are safer and ultimately more fun.
