Caffeine is drug and like all drugs you start to become immune and start needed more. For those of us in cannabis we have what is called a tea break. A tea break is when you stop using your drugs for a month or two to reset your drug tolerance. I would suggest not using caffeine for at least a month and see if that helps before having to go to a doctor if you are in the US.

If there is no ownership then there is no stealing/pirating by sailing the high seas.
