DUI's won't stop you.
Losing your job won't stop you.
The only thing that will stop you is you, taking action.
There are several things you can do that are not expensive. Meetings is one of those. You can go to a doctor and explain the situation. I told mine flat out that I was uninsured and needed inexpensive help. He gave me an inexpensive anti-depressant prescription. It's helped a lot. Also, was given a referral to a counselor that I haven't needed yet. And we discussed escalations that could be made if needed. All that cost was an office visit and $1 a day for meds.
Much better than a DUI.
