edit:just realised I'm answering a question you didn't ask but I'm going to leave what I wrote for posterity. However, consider my answer to be changed to be extremely careful of the choices you are making. Everyone is different and people do indeed move from being problem drinkers to non-problem drinkers, but they are probably pretty rare. I personally know the chances of me being able to fuck with my problem drugs again successfully are so miniscule as to be not worthing trying.
....anyway, what I was writing before I actually read your post correctly8
I'm about six months clean from crack/opiates/benzos/ketamine, I drink a few drinks now and then and smoke a joint now and then. It's been the most productive and comfortable six months of my life perhaps ever and the most comfortable I have ever felt in recovery. In all honesty something strange has happened with the booze, I drink a couple of drinks and then I really feel I've had enough. I stopped drinking totally for a while because I just didn't want to after getting off everything else, I had been drinking pretty heavily during my last round of using and then found it quite hard to stop drinking at a moderate level (a bottle of wine a night or so) after cutting down to there. It took a conceited effort to reduce my drinking from a fairly high level (3-4 litres 9% beer daily on top of my other substances) and I got stuck at various points where I found it very hard to break through to the next level of reduction, for a long time I had to have just one or two glasses of wine a night. After stopping completely I had no real desire to drink at all and still don't really, I wouldn't shed a tear if I couldn't drink at the moment and I actively don't drink if I think I am choosing to drink for the effects rather than the enjoyment of consuming the product. I actually don't like the way alcohol makes me feel much anymore, and certainly I do feel like it's poisoning me and making me unhealthy (which is exactly what it does).
I don't know what it is but for me something has changed this time round, both mentally and it would seem physiologically. Either way at the moment the use of alcohol and cannabis
is part of a successful and happy recovery. Far far more successful and happy then I have ever been trying to be 100% abstinent, but at the same time I get the feeling that I would be saying the same if I was taking the path of 100% abstinence. I can't explain it and I know this wouldn't work for everyone, hell I can guaruntee that it probably wouldn't have worked for me in the past. I'm aware I may be in denial and that maybe I will eat my words at some point some time in the future, but the same is true of any model of recovery. You can only do what seems to work for you when you find it and this is working for me at the moment.
I guess what it boils down to is that in a funny way there are more important issues to tackle than can I use xyz drug and stay good in my recovery sometimes. I've done some stuff and for the moment it appears to be having the effect of healing me of whatever was within me causing me to fuck myself up so badly. There are definitely some sacred cows in my recovery that I know I can't fuck with and I can feel that thing within me that wants to step back in to that world sometimes still and it terrifies me a bit because I know I'm vulnerable. At the same time I am dealing with it well at the moment and that gives me strength.
I'm rambling a bit here now (sorry!), but I guess what I'm saying is that there are no right answers to the question you are asking, but at some point it's probably wise to take the answet that gives you the best chance of success in your life at the current time.
