Welcome tjp! I very rarely stopped at one drink, or if I did, it was because it was the "appropriate thing" to do. I always wanted more. I suspected I had a problem when I saw how much I looked forward that next drink, but I KNEW I had a problem when I found it impossible to stop on my own.
You're at the right place and the good news is that things don't have to get any worse for you to have a healthy, alcohol-free life! :ghug3
