"Without taking into account any of the other factors, the formula below illustrates the LEAST amount of drinks remaining in the bloodstream:
A person drinking:
- 7 drinks in 3 hours would have at least 4 drinks remaining in their system.
- 4 drinks in 2 hours would have at least 4 drinks remaining in their system."
so, using that formula I can drink 10 drinks = 0 hours ago = and have 0 drinks in my body. I am good to drive.
