This is odd, but I have found that I talk more now while sober. I suppose part of me is a bit shy, but in the main, I am very intellectual, though extroverted, so that this over-rides my shyness. Many people have commented that I seem happier and chattier now that I am 40 days sober...I think alcohol had me in this depressive state, so much so, that it failed to act as the social lubricant that it used to. I still do go out, (and have sodas and like as opposed to alcohol) to talk to certain of my friends who happen to drink, and a lot of people have said, wow, you seem so much more outgoing. Which is odd, because there was a point I did drink to loosen up, but now I am finding that part of my self was there all along; drinking was masking it.
Then again, I love to talk, as anyone who knows me will testify to.
