Welcome to the forum hatleyn! I can't say I went through the anxiety, I was mostly just pissed at everybody, but I know a lot of folks here did. You're in good company!
Personally, for years I've been so sick and tired of being a slave to that little can. I can't tell you how long the withdrawal will last, but I can tell you life is so much better on the other side.
As everyone has said, be sure to post roll everyday and 1st thing in the day. And then get to know your fellow quitters and build that brotherhood. (There may not be a lot conversation going on in there now, but that'll change soon!) Jump right in the middle of it. Or hang out here in the intros after you been here a while and welcome new Quitters. Just get involved. And oh yeah, read read read. There's some good stuff in some of these intros.
Do a member search and check out Nolaq or wastepanel's intros and HOF speech. There's a lot of other great intros here as well.
You have my digits, put them in your phone, text or call if you need anything
Proud to Quit with you today
