I have always been able to drink as much caffeine as I pleased with no impact - it never gave me a buzz or a high, I drank coffee because I liked it, and didnt really drink lots - I like one cup a day and the odd diet coke.
However the last few weeks after a caffeinated drink I have started having what feels like my heart is racing, but its not? It feels like an anxiety attack without the anxiety.
Is that what a caffeine buzz is? Am I about to be forced to start drinking decaf? Say it aint so!
