You don't say where you are from and didn't complete your profile. Money costs vary from state to state. Many times you may do this and get home alright but it only takes once of hitting another car or tree and killing someone else to make all the fun you thought you had drinking go away.
First time - total costs - court costs, fines, lawyer, reinstate license after suspension, about $2500.00. Then whatever jail time you end up serving, a day or two. Second time w/in 10 years, $5000 to $7500.00 and 30 days at least.
