the withdrawal is really nothing, but i'm not sure you are aware how long lasting the metabolites are.

i had a condition called "gout" some years back that was related to dehydration and caffeine metabolism. it blocks up fine capillaries all over your body especially your skin.

i have again been seeing this, and gradually the blood vessels are clearing out. i've also been having odd problems with my teeth and part of that has been related to the way that caffeine's metabolites literally clog up your fine blood vessels.

caffeine is nasty stuff, a lot more nasty than you'd think. almost all of it turns into uric acid and clogs up your blood and kidneys for weeks after you stop.

this is also why many people are addicted to both caffeine and alcohol, as the alcohol thins the blood and reduces the bad side effects of chronic caffeine use.
