Glad you are back Thanos, and that feeling should subside once you get some sober days under your belt. Each return to drinking for me ended in worse and worse withdrawals, I hope this can be your last too.
Regarding the posting issue, there has been a problem with the site software and posting new threads. The temporary solution is to just use a one-word title. You can then go back and edit the title if you wish, but for some reason multi-word titles get blocked occasionally.
