I have worked with both alcohol and smoking addictions. I just get the OK to care for them and ask the OD for whatever priorities there are associated with the addiction and correct accordingly.

I also ask the patient to shut their eyes and to think about that first puff or drink and to imagine the feeling they get from it. This usually throws up a number of things - usually sphenoid and temporals - which I adjust.

I then get them to open their eyes and talk about some unconnected issues before repeating the process.

I go through that cycle again and again until there is nothing to adjust at which point the OD usually tells me that that is enough. It is hardly surprising that those bones come up because the part of the brain dealing with behaviour and addictions lies just beneath them.

The only prerequisite is a genuine desire to quit. Otherwise, we find the patterns are just re-established again.
