Nicky, just a word of advice regarding attending court and your demeanour whilst there. Dress smartly, suit etc, explain in a quiet unhurried voice that you have had depression and previous drink issues in the past and that you are deeply ahsamed and embarassed at what you have done but that it was actually a wake up call to you to see exactly how far out of whack your behaviour was and that it has caused you to stop drinking altogether and to get professinal help. Enrolling with AA or some other such organisation prior to your court date might be beneficial to prove it. Apologise, pile on thick anything that will help ( if you have kids, will lose your job, home etc) and just generally snivel to the bench and sound convincing and above all appear respectable so they think it's a one off and you've already learned your lesson.It's not a huge deal and if you do all the right things you should avoid custody altogether. Good luck.
