Whats done is done as far as calling in sick....I honestly would have recommended just saying that you are ill...as this is true. But I have not gone back to my boss and corrected the lie that all those times i called in drunk I really had the flu, a freind died, a dog sick etc.
For today just put the focus on getting sober. So good that you called your sober friends for help
I know what a tough call that is to make.
Please let us know how you are doing!
