O/T for T caffiene withdrawl

Been wanting to ask this for some time. I bring this one to you because I know you've posted related messages.

Not abreast at this point on whether you are currently on or off the jo, but my question involves what your experience is when you do drop coffee/caffiene intake. What type of withdrawl occurs for you? And what might you drink in leiu of coffee, black teas, etc's. when on the wagon?

Anyone.
