Yup, I used to. For probably 10-15 years. Got pregnant w/my now almost 5 year old, and just didn't really want to pick it back up. Smoke repulsed me while I was preggo, so it was easy to quit. I've had a few slip ups (think girl's weekend, devil-may-care, wine imbibing decision making) but sitting here right now? Don't have any desire or craving to seek it out.
Plus, knitting, quilting, baking, hand busy things make it impossible.
