Oh I'll take this one.
I considered drinking to be fun, part of how I made friends and took stress off. Most of my friends are in the hospitality industry.
At 37 I realized it was not doing me any favors, making it hard to stay in shape, always hungover, feeling bad about myself and just drinking and moping.
I quit last summer and the first thing I noticed is I had like 3 more hours every day in the morning being clear headed instead of hungover. That made it easy to quit (for me) and I really don't think about it much anymore.
