My homocysteine was low even when my lipids and bg were bad, and my crp
has fallen a great deal in the past year.

I'm not taking a chance of getting creamed by a truck tomorrow without
having had a cuppa joe.

Are you replying to me? You must learn to quote so folks will know what
you're posting about.

I don't want to cut back any further, nor do I think any harmful effects
are proven, just suggested.

Coffee is also rich in health protective antioxidants.

besides that I'm much more level headed and think much clearer then

My head's been clearer and my heart less wired since I gave up sugar and
starch.

I'll give up coffee when I'm dead.

While on the topic of coffee & studies, we were wondering if Starbucks had
any hand in funding this one ;-)

Caffeine is a drug used to treat apnea in infants. Levels must be monitored.
