YW Programmer27!
24 is the perfect age to quit. I have read that personality becomes set at about age 27 and any major personality changes after that will only occur after great emotional disturbance. In other words according to some developmental and cognitive researchers you are still flexible enough to be able to develop a different personality and mindset than a dependent one, be that on alcohol, people, or both.
I never decided to become an alcoholic when I was your age, it was not a goal. I was in control and a normal drinker for half of my adult life. And successful in all aspects. Then I decided I was set and could relax my discipline and drink when I wanted, I could afford it! Regression to binky time!
Just remember this isn't a try, it is the end, and if you commit to never again, you will make it. Keep posting and keep manned up on this. Real men work as a team. You're learning to be a team player. Welcome to the team.
