Welcome - great first step. make sure you don't have any hidden cans. Never again shall you dip, not just once. You can do this. Use the site. I was a 30 year idiot and now 904 days smarter. Day by day. Vent here, read everything, post up each day and keep your word.
Lots of people here to help. Use it and once you get thru the first few days you will feel stronger. Just keep in mind, it's a fight and the nic bitch cheats. Be prepared.
