AW's obsessions are mostly about health issues. She obsesses about getting cancer, but has no fear of the damage alcohol is doing to her liver. She also tends to hoard, or, more precisely, "stock up" on certain things. She used to be really bad about buying toiletries that we didn't need. As a result, we now have several hundred bottles of shampoo, body wash, etc. stashed in various places in the house.
I finally got her to stop that expensive habit, but since then her drinking has gotten worse. Maybe the compulsive shopping was a coping mechanism? Who knows?
