Serenidad, I don't think it's at all helpful to hear that anyone can lose their sobriety at any time. You need to be told the truth, and the helpful truth. That is this: Anyone can get sober at any time! And that means YOU. The question of difficulty doesn't really matter anyway, does it?
You know how to do it. Don't listen to the nattering nabobs of negativity who stand in your way. Make your stand, believe in yourself, and launch!
