Thanks! I drink an espresso every day, mainly out of habit, for over 40 years. I don't really get an energy boost (that I can feel) any more. I've cut back on all other coffee intake, just the espresso every morning. I've also gone without for a week or so at a time but not felt 'ill' for it. I have thought about giving up entirely, but not just yet.

Thanks again for the detail. Helps me think more clearly about what I want/need to do.
