With all the coffee deals going around, I'm curious to know has anyone from ozbargain attempted to and successfully quitted caffeine for good?
I have been drinking coffee daily for over 10 years and went cold turkey last Friday. Having big headaches and muscle pain, didn't know caffeine was so addictive.
Edit: just thought I'd add, although I do have the on/off headaches and muscle pain, my sleep has definitely improved slightly, and I'm not too sure if it's related but I'm seeing more dreams.
Isn't the half-life more like 6 hours? May vary between individuals of course.
