Good stuff dude! You have found a life boat here at KTC. It will change your life! Take alook at the Welcome Center thread. Read through those posts. They are short and will explain a little about how KTC will work for you.
I dipped for 23 years, and I'm quit for 144 days now. Was it hard getting started? Oh yes, but I had some motivation outside of just wanting to quit. Honestly though, this site, and my quit group made the whole beginning part much more manageable. I'm never going to be completely cured of this addiction, but I know that there is support here, and they have my back and I have there's. So, you want success? Follow this:
1. Post roll every day without fail. Do it first thing, and do it every day. It is the most important part of KTC, and you must use this tool. You have to ask yourself is coming here everyday for like 2 minutes going to be something you can commit too? I can tell you that there are those that stopped posting roll after having quit for 500 days, and they are right back to the poison. Can you commit to such a simple task? Don't have internet access? See rule 2
2. Get some digits of quitters in your group. I suggest the person above and the person below you in your quit group spreadsheet. Just pm them. It's very important. Out drinking a few with some buds watching the game, and you decide you'd like to sling just one in, but you know you shouldn't. Call or text them. They will talk you down, and you will do the same for them.
You said you have quit several times only to cave. That can happen here. There are dudes who have quit for 500 days, and then caved. Why? Because they stopped following the program. If you don't think you can spare 2 minutes a day to post roll, and then get some digits of other quit brothers, then I advise you to not waste your time here, but if you want to quit, and you can follow the program you will be quit for the rest of you life. Good luck my friend, and I look forward to seeing you in the HOF!!
