Hi mps,
I think denial is a huge part of addiction. And, recognizing the 'addict voice' is a big step in being able to deal with addiction. Once you know the voice and that it is your enemy, you can learn to disregard it and move forward.
The positives of sobriety cannot be overstated, in my opinion. Of course, it doesn't mean that every day is going to be wonderful. But, I have learned to know that the 'not wonderful' days are temporary.
