Why do I always feel ''high'' 15-30 minutes after ingesting caffeine? This feeling continues for about 1-2 hours after, and then I start to feel bad.

It can make you feel more alert and awake for a couple of hours, but then your energy might crash -- especially if you're very sensitive to it. It's also an addictive substance, the most commonly used in the world. ...Read more

Go to hospital now: 2, 340mg of caffeine? Over 4 days ago? Clearly it's not fatal (yet) in your case.
