I think it depends on the person and the reasons you undertook the process to begin with. I don't worry about drinking coffee. That's not why I went to detox or IOP. I smoke cigarettes and don't have any plans to quit at this point. That could change in the future, but as of now, I am a smoker. I went to detox and IOP because I drank too much beer and was beginning to find other alcoholic drinks I liked, too. This is what concerned me and this is why I went to detox and IOP. I no longer drink alcohol and so I feel like I have accomplished what I set out to do. Others may not look at it that way and that's fine with me. I didn't do anything for anyone other than myself.
