Was badly stressed preparing for the entrance exam for engineering schools. It was to the point I had heart palpitations for hours.

Two things made it disappear: - Sport, even just running an hour a week stopped the palpitations - Magnesium supplements

It's bearable for me because it won't last more than two years. Over the long-term, I would suggest trying to fix the problem from the inside (therapy? meditation? switching jobs?).
