Congrats to you on making a life changing decision you will not regret. You received some excellent advice here and I saw you were able to post roll. Great choice and way to figure that out! Now, just be a man of your word for the whole day. Before you know it, and despite the difficulties that will likely occur, you will wake up tomorrow and be on Day 4. Then repeat. After awhile, I promise, it will get easier. Post first thing in the morning and then don't break that promise to yourself or your fellow quitters.
This will not be easy to do! I also chewed a can of Kodiak everyday, all day (and sometimes thru the night) since the 80's (cue in Round and Round ....). You can do this, and will be better off for it! Reach out anytime you are in need and get this shit done. I sent you my number ... and no that doesn't mean I'm gay. I was new to the whole internet forum just a few months ago, but some reached out to me in similar fashion and got me through some times that I probably wouldn't have been able to on my own.
I'll quit with you today and look forward to seeing your name on roll tomorrow!
