My brother fights pain pill addiction and is currently in jail for his 3rd DUI. He's over 30 years old and still hasn't learned. Signing up here and posting is a great sign that you're ready to move forward with your life and you're still young so you can easily change your life still. I use to smoke, I believe I started when I was 19 or 20 and quit at the age of 25 with the help of Allen Carr. I'm only 27 but I've learned a lot in my life and alcohol was the most stubborn addiction I've ever had.
I hope you stop being stubborn at least for one day and call the doctor like you said you would, you have a long life ahead of you, don't waste it on drugs and alcohol.
