Thanks for the posts!! I am in the service-repair business, and am constantly around people who drink coffee and very generously offer coffee to me. I try to resist most times but I really like coffee. About green tea. I really like green tea also but find it hard to brew up some while on the road alot. Thanks also for the link to the caffeine site, interesting. A few years ago a M.D. that had a T.V. show mentioned that Coffee was a major problem for some people causing similar problems as mercury poisoning. (probably as Russ said awhile back in a post about caffeine helping mercury into the brain and I think converting it to methylated.) The doctors good suggestion was to get off coffee and see how you feel after a couple of weeks.
