Sometimes in life we must make choices. Many people have chosen a sober life after years of drinking and many have done so without rehabs and while they worked full time jobs. It takes will power and making some good decisions. Sitting in bars and hoping not to drink does not qualify as a good decision.
If you want to stop then you will. Find an AA meeting, they are right in the front of the phone book, walk in, sit down and start getting sober. I did just that 14 years ago. No rehab, worked my job and took one God awful amount of very long walks whenever I wanted to drink. Hated AA for at least the first 30-60 days, about 90 meetings, plus or minus, but I had a lot to lose and decided it wasn't all about me anymore.
I am not special, there are many just like me, but it is difficult, not impossible.
Good Luck,
Jon
