When I started out I was a part time binge drinker, getting drunk on the odd weekend at a party. When I started working 5 years ago I started having a whiskey or glass of wine after work every evening to "relax".
Eventually that escalated to a few whiskeys or a bottle of wine a night. When I stopped getting bad hangovers, I thought I could drink with no problems. I drank every night to black out point, I drove my car under the influence many times and luckily I did not kill someone.
Then the anxiety started and I knew I could not drink anymore...
