GBE - I can do the same thing and look back at my posts from 2013, we both joined the same year. But like Jay-Z says, gotta learn to live with regrets. Ha.
I don't think looking back does anything for us unless it spurs us to further action. You are still young at 28 and have so much of your life, all of your adult life, ahead of you. Make that life sober and something to be proud of.
Always good to see you on SR.
