As someone who worked in the adult beverage industry for 7 years, I completely agree.

People who work in the industry have access to all this beer / wine / liquor for reduced cost or free, so drinking every day is normal, and then you spend each waking day with a semi-hangover and are a little worried you may have said or done or posted something dumb the evening before, creates a downward spiral of depression, which then makes you drink more.

It is no way to live, once I reduced my drinking habits back to 1-2 days a week, I felt like a human again, and woke up feeling well-rested, which in turn made me less depressed, and gave me loads more energy.

Edit: To people commenting or believing that this is alcoholism, actual alcoholics don't last more than 3 months in this industry, ever. Most never make it the first 30 days. They lack any self control over their intake. There's a difference between drinking every day and being drunk every day.
