I took 300 mg of caffeine in feb.i reacted badly with fast heart rate and shaking.i did not go 2 er. i still feel bad.what possible damage occurred?

Unlikely: it would be very unlikely that any damage has occurred based on what you have described. other over the counter products such as pseudofed can have similar effects as caffeine. as well as foods and beverages can also have lower doses of caffeine that could be contributing. hope that helps
