why give it up? why not mix it up? I usually drink a cup of green tea one day. a cup of black tea, another a cup of coffee, another iced coffee another spice it up life's too short
I feel like coffee gives a quick temporary boost but then hits hard and slows down so I have to drink more and more
It's a drug, it certainly hits everyone differently. Getting enough sleep the night before is more important but not always possible. I was up until 1:00AM last night replacing sway bar endlinks in my car and had an early 7:00AM meeting. So it's a coffee day today.
