Lots of people go about a year and think they're "cured." WRONG! The Nic Bitch is relentless and crafty. I don't have all the answers, but I have one...posting rol.
I posted 2 years on Sept 11, 2012. KTC (and you folks) are now part of my daily routine. I might miss a day here and there, but not many. This site is my new normal.
Do what works for you. But I will tell you that I've seen many with your story who wind up posting Day 1 again because they thought they didn't need roll call anymore. Maybe I don't need it...but I'll never know. I was a slave too long to risk going back. Posting roll everyday is the key for me...and it will work for you.
