I very rarely drank in my 20s. Didn't even have my first sip of alcohol until I was 22 or 23. By 30 I could count on one hand how many times I drank. In my early-mid 30s I discovered that the buzz I got from cigars was nicely augmented with a cocktail. Then it slowly evolved into high proof bourbon on weekends, then on to a few rum n cokes every night (50/50 mix in a pint glass). Now at 42 I can't drink a single rum n coke without my stomach feeling super bloated without even getting a slight buzz. A few months ago I realized I was headed for a big problem so I cut down a lot. Presently at most I'll have something clear like a gin and tonic, and only 1 per night max. My goal is to break the habit I formed not too long ago of daily drinking and go back to only weekends, and then to hardly at all. So far it's working. Cold turkey isn't really something I can do, but making a plan to ween off it works for me. One of the biggest hurdles is to get my wife to do the same, as we are a bad influence for each other in that regard.
Financially speaking, it's terrifying to see that I've spent $4-500 a month just on booze.
Health-wise, it's dehydrated my body a lot. I already have a hard time staying hydrated normally, and alcohol just plain dries me out after hitting liquor hard night after night. Cutting down on the booze and being conscious about drinking more water during the day done a lot of good just on that alone.
I can't imagine how I'd be if I had been drinking like that for the last twenty years instead of just the last few like it has been.
Don't get me wrong, I enjoy a good buzz - but spacing it out makes it a better experience with less effort. Drinking every day is just chasing the dragon and not worth it.
