Welcome Adam... As others have said WP has given you alot of good info.. Now its time for you to get pissed at the NIC WHORE and fight like hell. Get some digits of your quit brothers so you can call / text each other when you need support.
You will hit the SUCK first... The first 10 days or so will be the worst, but each of us quitters on here are proof that you can do it!
Best advice I can give, get digits, get active in the site, quit like fuck every day!
