Alcohol and I had some good times together. We also had some really bad times together. For a while the good times had severely outnumbered the bad times, but the bad times were catching up fast. I struggled with trying to control my drinking for a while to no avail, so after yet another bad night it became apparent that I needed to stop. The only way to keep myself from having drink #10 was to not have drink #1.
And with that I quit.
