Most importantly, I have cut out caffeine. I used to drink
coffee in abundance, but not anymore. Some of the worst episodes of tachycardia I have experienced have been triggered by that delicious yet troublesome substance, caffeine, so I started to avoid it altogether. The other day, however, I was feeling OK, so I went for a vanilla latte at the cafe near my house. It was a double shot of espresso, which is reportedly 150 mg of caffeine.
