Rabbi A.J. Twerski has a book called "Self-Improvement?! I'm Jewish!!" in which he explains that the 12 steps are all tools that are also brought down from our own Torah Giants and they were put into a combination that has proven to be successful.
There may be things that they preach in 12 step groups that come from christianity, I wouldn't know since I haven't been to meetings, but in essence there is nothing in the 12 steps that is against our tradition.
Regarding your title "are there side effects?", I have experienced side effects, I've actually become a more diligent learner, spend my time much more productively, I am more friendly at home and in public, and I'm sure I could add many more side effects to working the 12 steps.
As for your question, I think that you can address it the same way you address any of your other defects. I found by me that the reason that my learning got better was because I saw it as an extension of what Hashem's will was, which is, btw, the basis of the 12 steps. I stopped learning because I wanted to learn (which was also why I wasn't learning so well, because there were other things I wanted to do as well) and started learning because that's what I'm here to do!!
KIT!! KOP!!! KOMT!!!
