Cross addictions are a risk for WLS patients -- not guaranteed, but a risk. When we don't have food to soothe us anymore, we may use other substances to soothe us post-op. This risk extends to people who are not alcoholics pre-op. In fact, someone posted here recently who had become an alcoholic post-op who had never even drunk socially before surgery.
Again, it's not guaranteed, but a risk.
I've just read that article and it's very interesting thanks Ann
