Thanks for the stories and encouragement, all! The more I think about it, the more I think I might have done something to inadvertently cause my death if I had continued. Aside from all the health stuff anyway, I guess. And I wouldn't consider smashing my face into my tile floor the worst thing by far. Oh well. It's all done now.
I'm pleased with the weight loss but not drinking 2-3 bottles of wine a day will take some off with little work at the beginning at least. It's slowed down considerably now, of course.
