Hang in there Charliee! When I had 10.5 months I slacked off on what was keeping me going, my husband relapsed and then I shortly followed. October 1 would have been a year for me. I am back again, one day at a time and i am shy of thirty days. Perhaps you are going through the seasonal doldrums? I found that with each season or holiday that came up I was experiencing it sober for the first time in a long time and you are facing the Triple Crown of drinking holidays, thanksgiving, Christmas and New Years while sober which is added pressure.
Go back to what has helped you get this far and add something different to shake it up a bit. You are doing great if you have gone this far. Do what was working for you. Post here for support. I didn't have SR back in August. It really helps keeping me sane and sober.
