hi SJ
I drank for 20 years - it took a little time for me to learn to live sober - months not days.
I'm alot older than you but I had the peer pressure thing too - my city is a big drinking one too.
but...if you're a drinker, you tend to hang with drinkers...now I'm not a drinker I'm constantly surprised by how many non drinkers, or normal one glass drinkers there are.
The bottom line is I needed to make changes in my life if I wanted to stay sober.
I guess the question for you is how much change are you prepared to commit to?
