first attempt quit?
Read everything on the site and hang on for dear life. when you don't think you can take another second, just hang on a tad longer, and another second and so on, until it's another day. Don't get hung up on anythign other than getting through one day.
I did not do this, but in hind sight wish I had, write down how shitty you feel during the first 3 days. I was in bed for my first 2 days, and essentially couldn't move. Yet once the fog cleared, my addicted side says to my rational side... "that wasn't so bad, lets have one more dip". THis is no joke, it will be tough, write down why you decided to quit. Your resolve will be tested. Your brain will try to get you to cave in every conceivable way.
Post roll call daily. Know that roll call is you giving your word to not dip. People on here treat a stranger's word like their family's, very seriously. So when you say you won't dip and cave... lots of people are pissed. Don't cave, you'll feel douchy, guilty and defeated.
That said, i'm on day 9 and would say that the cravings I deal with daily are 1/100 of those I faced on day 1-5(I dipped 1-2 tins per day). So it gets much better, much faster.
