I agree with FeelingGreat... Timing is everything. I've set dates to quit, been hospitalized, and had plenty of instances where I knew I needed to quit but if I wasn't really "ready," I didn't follow through. This time around has been my longest stretch of sobriety and it wasn't even planned. Yet I've been more successful at sticking with it bc it was the right time. You'll know when you get to the point where it just feels right and when you do, support is everything. Spend time here on SR, find new activities, and take it a day at a time. Good luck!
