I have been where you are....I got myself to the emergency room the first time (don't drive...take a cab). The last time I called someone from AA to drive me to a 30 day treatment center. Just said the heck with my job, my house and my family.....I was out of options....
Best thing i ever did....and i knew that by the time i was 2 mos sober...i'm 14 mos sober now and as Matt refered to...i now have purpose and meaning in my life....It is a wonderful journey with a scary start!
Please call your doctor.
