I think I've found a painless way to explain to people why I don't drink

I have a work trip in February to go to a convention in Houston, Texas for a few days, and there will be drinking at the convention, and outside of it. It makes me nervous only being 3 weeks sober as of today.

So what I plan to say is:

"Ya, I tried dry January, and I decided not to drink anymore because I liked the feeling of not drinking."

I think this is painless, and really doesn't open the door for any prying, or harsh judgements. Hell, I may use it my entire life just for casual encounters.

What do you guys think?
