I can answer that question in 7 months but I'm still going to chime in anyway.
I don't think your ability to remain sober is based on use or non use of a program. It's based on your willingness to put sobriety ahead of drinking no matter the circumstance and your capability to be "TRULY" honest with yourself. I say "TRULY" because as alcoholics we are all known to invent reasons to drink and lie to ourselves about why we should, conveniently forgetting that we are on a mission. The power of commitment is never the same on the day that you make the decision to quit as it is when those urges arrive. Honesty with one's self is the key.
If you know that there are times that you are going to have urges where you will lie to yourself and need to depend on someone else for direction then it's best to look to a program or find a consistent means of support. Someone who can take the reigns for you when you aren't being honest. Even still, it's up to you to reach out when that happens.
Do your research and find what works for you. It all comes down to you.
