When I stopped drinking, most of the people in my social circles didn't even notice. They were too drunk. Those that did notice were for the most part relieved. They knew they wouldn't be breaking up a fight, running out of Irish whiskey, or cleaning up the bathroom.
If you're new in Texas and they question why you aren't drinking, just tell them to shut up and mind their own business. They like that in Texas. JUST KIDDING! I'm feeling a little weird this morning.
Not to make light of this - when I first stopped i was worried, too. Try going, let people know. Heck, tell everyone you take your softball really serious and you're in training. Just don't drink. That's the real thing to worry about.
