I had heart/chest pains from Lisdextroamphetamine (ADHD meds) that went away when I stopped drinking coffee. And I drunk very little, just one half cup in the morning.

Much less anxious now too, but that's more likely due to ADHD meds.

Even on the "milder" Methylphenidate you can experince clenching jaw, grinding teeth and a chafed tongue when consuming coffee, tea and even dark chocolate.
