Oh this is so interesting. I'm an alcoholic in recovery and in AA for the past couple of years. Got sober in a rehab though under serious medical supervision (no doubt in the least I was an alcoholic!) and thank AA for keeping me sober. So them's my credentials so you can tear me apart a bit more effectively. Oh - I also have lost over 4 stone in the past year and a half by eating less and exercising more.
I come from a slightly different perspective than Kokeshi - this challenge seems to me to be more like my losing weight thing. I don't have eating issues or any health issues related to weight, so willpower and planning were enough. It seems to me like an extreme version of that 10 years younger in 6 weeks or 10 fruits and veg a day thing. I think a year is a very long time, but not because it's alcohol, just from the goal-setting standpoint if that makes sense! If you realize that alcohol is satisfying some deeper need for you and you can't deal without it, go from there.
My view of AA is that it's very good, free, easily accessible group therapy with a program that works for me. I won't get into the god thing except to say that I don't have a god and it still works for me. But I'm not only agnostic but apathetic so that view works for me. I'm still very comfortable in the program (the same way I'm comfortable around friend who are religious in the traditional sense). I have an inkling that it doesn't work for everyone and I'm certain that not every individual AA group is for everyone (it's kind of like finding the right therapist).
The best thing about not drinking for me is not that I'm sober and can actually function (that is fantastic, admittedly!) but that I've lost the obsession with drinking - I thought about the next drink all the time.
I realise I'm babbling on - that's what knowing how to touch type as fast as I think can do (I think slowly so my fingers can keep up). Good luck and have fun!
Ooh- I do have a tip. If you're drinking a bit, you're getting lots of sugar. If you find you have a craving, sometimes a candy bar will take it away. Don't overdo it though! And remember to give up the candy bars after the cravings stop. If you'd like, I mean, there's nothing intrinsically wrong with eating candy bars.
