First, thanks for your service, Bike. Second, congrats on making a great choice!!! My two cents...
You said that we're "a bunch of people I don't know." REALLY?!!! I think you do. In fact, I think we know each other pretty well...tired of dipping, googled "how to quit," found this site, like the no non-sense approach, lied to ourselves about quitting in the past, knew we had to quit but justified "one more" for years, started when you were young because your were bored or thought it was cool or something? That pretty much describes every person on here.
Now, take it one more step...look at the Quit Groups. Look at all of those names. They all have almost identical stories as you. And they are all living free ONE DAY AT A TIME like you can too. They were all once where you are right now. They all know what you're going through. They all have your back. Would a stranger make that kind of commitment to another stranger? I don't think so. You are among friends here...exceptional bad-ass quitting friends. So, reach out, get involved and enjoy your new life.
Post roll, give your word, read everything you can. YOU CAN DO THIS, BROTHER!!! Oh, and nice to meet you, too.
