Several years ago I was going through a rough time in my life and started to have a drink when I go home from work. At first it was just a single drink maybe twice a week, but grew from there. Within a few months it grew into problematic territory. It never got to the point where it was interfering with other aspects of life and I didn’t ha e a physical dependency but I eventually recognized the issue.
Looking back it was clearly a coping mechanism. But the bad thing is how gradually it stuck up on me, and how long it took (About a year for me) to recognize it as a problem. The line I think is very much thinner than most of us think.
