Depending upon the alcotest reading, it's a loss of license for 3 - 12 months, a fine of $250 to $500, participation in the Intoxicated Driver Resource program, a term of imprisonment of not more than 30 days, the possible requirement to use an ignition interlock in your vehicle once the license is restored, and some pretty severe insurance surcharges.
Get a lawyer. While these charges are hard to beat, a good lawyer may be able to find an error somewhere that could result in lower levels of fines and penalties, or even in some cases, dismissal.
In general, assuming no accident/injuries your looking at up to 30 days in jail (rare but possible) up to 12 months loss of license depending on blood alcohol level, fines and 12 to 48 hours IRDC. Get yourself a good lawyer and you should be able to win or reduce these penalties.
