"F**k yeah," writes Nikki on Tuesday. "Today is my sobriety birthday. By letting go of self and ego, working a program that connects you to a higher power and giving back to those still struggling are just some of the important things you learn through sobriety. You get to repair the damage done from drink, drugs and horrific behaviors that broke people's hearts who loved you."

"For me," he continues, "taking away the substance just gave me a honest view of who I had become and then the healing started. I do believe without any program to help, many are just dry drunks and there is always a danger of them going out again. I've been there. It's not pretty.
