Hi Char, what ever you decide to do- put thought into it and make sure you have support. There is a lot of info in the Newcomer's sticky's on your questions about plans, Christmas and health.
The only point I would raise- for me, I had to stop booze altogether- no compromises, and I needed a lot of support to do it- meetings, SR, counsellor, journal, research, GP.
Support to you.
