Thanks for the response. I am male, 39 years old. I have suffered chronic Depression (dysthymia) for many years but this has lessened signif. with lifestyle changes. I now generally eat vegitarian foods including a fairly high amount of live foods. I am now growing sprouts and eating a lot of these. I can't say I really excercise much. I walk a mile to work and back each day and often take walks during lunch break. but that's about it for excerise (although I should mention I have a four-year old that keeps me running so to speak!) I had my thyroid checked with a blood test and it came back "normal" but I have not done the thermometer method. I will try that. Thanks for the feedback.
