I spoke to an environmental engineer once who makes recommendations in how to make your home healthier if you suffer from chronic illness. It is interesting because she said that the flourescent lights are no good for people with mercury issues, and I never understood the reasons behind it either. My husband always says we should put flourescent lghts in the kitchen, and I won't let him. He thinks the whole mercury connection to flourescent lights is ridiculous. It's interesting because when I was in graduate school in my early 20's and first suffered from mild depression, whenever I used to walk down the halls of th building I did a graduate assistantship in, I would feel lightheaded and depressed. I knew there was something then too. That was 15 years ago - never would have realized anything about mercury or what the symptoms would have escalated to today!
