Welcome home :-) I'm glad you found us.
If you've been in OA for 20 years, I won't be the first person to tell you: Get a sponsor, work the steps, come to meetings, and call someone before that first compulsive bite. Might sound cliched after 20 years, but it works if you work it.
Many people here have found online meetings to be helpful in getting back into the swing of things. There are online meetings every three hours, around the clock, around the world. To enter the meeting room just click here: http://www.starchat.net/chat/index.php?chan=oarecovery
Also, TRG has many online sharing loops and workshops - some have daily questions and sharing topics, others weekly, and some are just for now and then. There's something for everyone. You can check us out at www.therecoverygroup.org.
