Caffeine pills gave me heart arrhythmia for like 2 months. I had to wear a monitor and everything.
Pill form is so much more potent, and I was splitting them, effectively bypassing the coating that helps it dissolve slowly. Your body is just not meant to absorb 150mg of caffeine instantaneously. Crazy I know.
With the premise the OP presented, I expected something worse than what was actually there. It was still horrible, but the impact was lessened for the reasons you listed.
Interesting how someone can manufacture consent like that by shifting your initial view.
