No I did not quit cold turkey or swear off caffeine altogether. What I did was to decide to slowly cut back. Two weeks ago I had taking one liter and a 6-pack out of my weekly diet. This past Saturday was my first full day without caffeine. What about Sunday?? I tried. I made it a few hours before I caved it.
The great thing about running is that when I run, I don't have the I need caffeine feeling. My end goal is to have less caffeine. I just want it to not be the first time I have to have everyday.
