If you drink 560 units of alcohol in 20 days how long will it take to come out of your system?

For people of European heritage, A unit of alcohol will normally be metabolized in about one hour so 20 units would require 20 hours before you are free of alcohol.

However, there are some human cultures where ancient tradition was to boil water for drinking rather than using brewing to sterilize it and this has lead to some genetic selection in the human population. Some people of East Asian and Native American descent lack a genetically coded enzyme that breaks down alcohol efficiently and the time it takes for these people to get alcohol out of their systems may be longer.
