Count me among those who believes that your success or failure is going to have far more to do with your personal desire or commitment to getting sober than with any particular support method you follow.
I hope SR is going to be enough to keep me sober (I have 33 days today) because it's pretty much my sole means of support at the moment. These forums keep me mindful of and focused on my sobriety every single day. It's a bonus that I actually ENJOY coming here to get and give support and that it's available 24/7. I just have to remind myself regularly to APPLY what I learn here and that my main purpose here is not to be entertained or impart wisdom or even share experience but to STAY SOBER. Otherwise I'm of little use to myself or anyone else.
