Well you should not have been drinking alcohol on probation. So you should be prepared to heed the Judges warning and he will most likely sentence you to 9 months in jail. As with any action such as alcohol there are consequences.

You should hire an attorney to represent you in this matter. You also should stop making statements online, as the things you say can be used against you.
The judge may, in fact, sentence you to 9 months in jail. Before he does, however, you have the right to a hearing on the issue of whether the state can prove that you violated your probation. You also have the right to a hearing regarding what your sentence should be. At your sentencing hearing, your attorney can tell the judge all of the reasons why sending you to jail for 9 months is not an appropriate punishment. Your attorney can talk about your family, your remorse, and your successes as a probationer. Your attorney may also be able to work out a deal with the prosecutor before you ever get to sentencing.
I have to believe you were represented by an attorney on this DUI charge. Speak with himj or her now. No one is in a better position to give you advice on this than the attorney who represented you on the initial charge. Further, your attorney will be well acquainted with this particular judge and will be in a good position to answer your question (e.g. what kind of punishment am I looking at?).
In the unlikely event you are not represented by an attorney, retain one now! A local attorney who practices before the judge in question would likely be best.
Get back into that DUI course NOW and get as many hours completed as you possibly can. Perhaps the judge will give you a break if you are committed to your rehabilitation. Saying you want to change is one thing, but making real efforts toward change is quite another. Good luck.
