Mother was my "environmental stimulus". She's dead now. I have got rid of her. I'm a non-practising alcoholic too - sober for 22 years - but the feelings which drove me to drink are still there. I would say I am completely over any addiction to the tobacco "extras". My parents gave me mercury to play with when I was a child, fabulous, fascinating stuff! It tickles when you run it around in your palms, it's so weirdly heavy, and when you hit a blob of it hard with a ruler, it shatters into tiny blobs everywhere, and then you can get them all to run back together again.... I do have mercury fillings, but they don't bother me. I can't afford yellow ones. (I don't have whitened teeth - I think they look like dentures and I don't want to mess with my enamel.) I have been told by my dentist that there is more danger involved in getting them removed (because it's drilled into an airborne dust. so it has a huge surface area) than keeping them in as they are. It's also something I simply could not afford. Removal of amalgam fillings is not something encouraged in the uk; dentists don't want to be exposed to the dust either, and it's only available in private practice - at huge cost. I did ask about it, years ago, thinking it might be a good idea because of the ME. The real danger with mercury is not really so much the metal itself (although safety rules and regulations are much stricter than they used to be, I'm not saying it is safe) - but when it becomes part of an organic molecule.
