I have a life-long history of high caffeine dosage. When I was a kid I drank lots of tea which in the long run desensitized me to caffeine, so now I can't even feel a full can of monster energy. I recently started having chronic OCD-like anxiety due to some life events and I'm not sure if the caffeine is contributing to it despite me not actually feeling the stimulant effects of the caffeine itself. Would quitting caffeine actually have any effect? I pretty much only consume caffeine because I like the taste of coffee, nothing else.
