Over my dead body.

I love coffee. I always have. It has anti oxidant properties. Don't drink the crap coffee. Most Americans have no idea what good coffee is. They're as educated with coffee as they are with nutrition.

Just drink less of it if you must but enjoy it. Get good coffee. Avoid it after 3 PM if you want good sleep. I found a late night cup after a dinner with friends typically sets me right for the drive home and does not damage sleep. But between 3 and 9 PM it's not great for sleep.

Finally it's important to understand that caffeine does not give you energy. It only hides fatigue. If you have trouble sleeping then avoid caffeine. You can get good decaf options today. But they still contain approx a fifth of a regular cup's caffeine.

People just have different tolerance. Coffee strictly before noon works well for me.
