I joined SR in 2012, and I hit the 90 day mark and then relapsed, I spent the next there years alternating between failed attempts at moderation, and periods of sobriety, and each time I logged back in here and relied on the support of the amazing people on this site.
I know how difficult it is to log in and post a "Day One again," . I would not have 21 months sober now if it weren't for the caring, supportive advice and comments of others on SR.
I will always post a supportive message to someone struggling whether it is their first time logging in, or their 1000th time starting again. It just may be the time that makes a difference, they may need just that one encouraging word to get through the day.
